Hi all,

So I've got F500BT with ND-G500 amp. There are 3 cables going out of the ND-G500. Two are said to be installed into "car stereo" and one "into car".

Does anyone have any idea where "in car" third needs to be pluged in? Also - the cables going from Pioneer amp have more pins that Metra Harnesses (Pioneer have 8 pins, Metra harness has 4 on one end and 6 on the other). So what's going on here?

Anyone in audio install business here? Can someone help out?

Here is a pic of the Pioneer harness that comes with the amp. No Metra harness i've seen will fit this. Plus Metra harness for Toyota has 6 pins, when two of the small plugs on Pioneer have 8 wires (4 speakers on one plug, and 8 different car signals (mute, ilumination, brake, power, etc) on the other plug

there are 3 plugs in your picture. I refer to them as left, middle, right plug. They are all Pioneer specify harness, chances are you will have to cut the wires off from the plug. In my case, i cut the red, yellow and black wire from the "right" plug, and connect to the red, and black to my factory radio harness. the yellow wire goes to the battery directly. Then you cut the 4 set of speakers pairs from the "middle plug". (total 8 wires). And splice it to your factory radio harness, that goes to each of your speakers. the left plug is for those who wants to keep existing factory radio to work in conjunction which the ND-G500 and F500BT combo. If thats the case, cut those 8 wires from the "left" plug and splice them to the factory radio line-output 8 wires. I left out the "left" plug untouch in my setup as I am using F500BT as the only source of music.

Those plugs are not Pioneer specific, but they are Euro specific ISO connectors

O.K., then how do I get adapters to hook to an American Ford vehicle so I can use this device with my factory stereo? I have done many car audio installs, and can manage, but I like to keep it clean and neat using the original factory harness. I searched thru Metra, but that didn't give any useful results. Can anybody help with these adapters?

Would the adaptors from this site work?

I am thinking of adding a ND-G500 to my 08 Saturn Vue. After finding my harness, I am trying to ensure that this has all the connections needed for the ND-G500. Please let me know if any of you have used this option. I may just order it this weekend and let it known of my experience.

JM,

From what I can tell, those are specifically for Parrot Kits. You need to find out what your vehicle specific connectors are (lets say 'US Conn') and then find an interconnector that is US Conn>ISO compatible. On the ISO connectors (there are two) one is for speakers, one is for power etc.

If those Parrot kits have what I describe above then you're sorted, so check on their site for your vehicle.

They look like just what the Dr. ordered. I have ordered for my install and will let you know how it works out. Thanks for the linky.

I installed the ND-G500 with the F500BT in a 2008 Armada and...best of all did not cut or splice into a single vehicle wire. Here is what I did:

The ND-G500 connectors are ISO connectors. For the female connectors, I bought a harness - i believe made by metra, but I could be wrong - but I looked it up on the internet and found it as standard ISO female connector. The male connector is actually the same as the VW standard harness.

I also bought a pair of nissan harnesses made by scosche to attach the ISO harnesses I mentioned earlier to them and plug these harnesses into the vehicle and factory radio and avoid cuting or splicing.

I had also heard about them being the same as the parrot connectors, but I don't know about this. Hope this helps,

I finally did my install today on a 2004 Mercury Grand Marquis.

The ISO adapter from the NG-D500 to the parrot quick connector had the red and yellow wires crossed. I don't know which one had it wrong for the always hot to the ignition/acc hot.

I cut and spliced the amp harness to the parrot connector for my radio anyway, and so corrected the above mistake. The amp wires to the parrot harness were 10' long, so my process shortened them to about 2'. The factory wiring and radio are intact with using the amp to parrot splicing.

The indicated parking brake wire of violet/white turned out to be brown/black, but otherwise went O.K. I did not hook up the reverse gear detect yet.

So far on a short ride all works well. More testing to come, and a 2003 Ford Explorer Sport Trac install in the future when I get the necessary install parts.

Hello,

I'm pretty stumped about the install of the ND-G500. I find the manual completely lacking, but that may just be because I'm a noob.

I was hoping you guys/girls could help me out with a couple of questions.

As far as I can tell, the ideal way to install (with no splicing), would be to get a connector from the current stock radio harness to ISO, and connect to the amp. Then get another connecter for the 2 "output to radio" connectors, and connect the amp to my car radio (Xterra 08, but this is just a general question about install). But, this leaves me with a lot of questions

1) How are you supposed to connect those 2 ISO outputs from the amp to the car stereo? It seems strange that you have to connect those 2 outputs to your existing radio,which has just one receptor. Do they make a 2-ISO harness that will connect to a stock radio? I haven't been able to find one.

2) from what i have been able to find out about the wires going into my stock radio, it does not have a mute, reverse gear signal, antenna, or speed signal. will this be a problem, or will the amp+F500 combo work fine without those? If not, do I need to dig deeper into the car to find those and connect the amp (instead of trying to connect the stock radio wiring/harness to the amp?

3) is +12 V the "battery backup", "yellow" wire on the G500?

Thanks for any help.

One of the connections is from the radio to the AMP, the other goes back to the car wiring harness. There is a double ISO connection for each.

1) How are you supposed to connect those 2 ISO outputs from the amp to the car stereo? It seems strange that you have to connect those 2 outputs to your existing radio,which has just one receptor. Do they make a 2-ISO harness that will connect to a stock radio? I haven't been able to find one.

I was able to find one via the quickconnector link above. Search around for your manufacturer's connector. The connection to your radio splits speakers and other connections to separate ISO connectors. The Always hot, keyed hot, ground, dash lighting etc. are part of the 2nd. Now one pair comes from the car harness to the adapter, the 2nd half goes to the adapter to the back of the radio.

2) from what i have been able to find out about the wires going into my stock radio, it does not have a mute, reverse gear signal, antenna, or speed signal. will this be a problem, or will the amp+F500 combo work fine without those? If not, do I need to dig deeper into the car to find those and connect the amp (instead of trying to connect the stock radio wiring/harness to the amp?

You don't need: mute, car antenna, or speed signal. You don't need reverse gear signal unless you want a rearview camera hooked to the F500. I "think" you don't need the cradle external antenna unless you use the MSN service. The parking brake signal is for safe use of the product that you can't access some features while you are driving that divert attention from driving. It is safer to hook it up, and may prevent loss of insurance claims if you knowingly use it against manufacturer's instructions.

3) is +12 V the "battery backup", "yellow" wire on the G500?

Not sure about this question, but Yellow is to an always hot connection, the red is to an ignition/ACC hot (key in turned to ACC or engine on).

Thanks sgthawker,

Very helpful. If you don't mind one more question....

I found a kit for my car QCnis-2.

It has one female harness to accept the male end of the original car harness. that makes sense.

Then, it has 2 single-ISO harnesses, and one double Iso-harness, as well as a male factory style harness to plug in to my radio.

OK...here's where I was hoping to get your input. Do two single ISO harnesses go into the double-ISO harness on the ND-G500? Do the two single-ISO harnesses on the Pioneer ND-G500 go into the double harness on the parrot kit?

That seems too easy! Are there any other male-female converters necessary?

My main point of concern is that I see that the two factory harnesses have wires connecting them (looks like they are power wires that bypass the "loop" of iso connectors). This isn't called for in the pioneer diagram, since all wiring is supposed to go directly into the double-ISO slot (i realize this is because the QC-nis2 is for a parrot bluetooth setup). Do you know if those wires connecting the two factory harnesses are just duplicates of what is also routed to the two single-iso harnesses? It seems like there shouldn't be any direct connection from the original harness and the factory radio, which would happen with this harness setup (QC-nis2)...did you cut these, or did you just not use one of the ND-G500 single iso harnesses (the one with power wires).

Thanks again for your help.

Brandon

Hi Brandon,

You said your radio does not have mute, reverse gear signal, antenna, speed signal, then you don't need to

worry about hooking them up. Your ND500 does not need them to operate properly. the red+12v, yellow+12v, black(ground) you should have identify easily. The difficult part should be to identify which 4 pairs wire go directly to speakers side, which 4 pairs is from factory radio output.

Then, it has 2 single-ISO harnesses, and one double Iso-harness, as well as a male factory style harness to plug in to my radio.

 

OK...here's where I was hoping to get your input. Do two single ISO harnesses go into the double-ISO harness on the ND-G500? Do the two single-ISO harnesses on the Pioneer ND-G500 go into the double harness on the parrot kit?

That's it! Very easy. The only problem I felt I could address was the length of the ND-G500's harness. I needed near 2' and it is 10'. The power inversion of the connectors may have been the Quick Connect's harness.

My main point of concern is that I see that the two factory harnesses have wires connecting them (looks like they are power wires that bypass the "loop" of iso connectors). This isn't called for in the pioneer diagram, since all wiring is supposed to go directly into the double-ISO slot (i realize this is because the QC-nis2 is for a parrot bluetooth setup). Do you know if those wires connecting the two factory harnesses are just duplicates of what is also routed to the two single-iso harnesses?

You do need some of these bypass wires for the radio. What ever was originally available to the radio is still needed. Some of the wires may have been in your car's harness for a navigation radio that the F-500 does not use or that your "normal" radio does not use. The radio still needs power (hot & keyed), ground, & illumination, at least. I used a wiring diagram for my car to determine what all of the wires in the original harness were.

Good Luck!

The difficult part should be to identify which 4 pairs wire go directly to speakers side, which 4 pairs is from factory radio output.

Actually that is easy. The harnesses are male and female. You can't hook the car harness to the input from the radio side of the ND-G500. It won't fit male to male or female to female. Now cutting and splicing the wires can be more difficult if you don't properly identify wires before cutting off the connectors.

Hi again,

Thanks so much for the advice. I'll go to Fry's today and try to find the adapter.

One last question...just to be 100% certain. I was a bit concerned about having two sets of power wires, etc (non-speaker wire) heading to the radio.....one group of these power wires being through the ND-G500 loop (ISO connectors), and the other set connecting the two factory style harnesses ( in the picture, it looks like these power wires are directed both into the ND-G500 loop via an ISO connection, and also "skip" the loop of ISO connectors by being directly routed to the factory harness that plugs into the radio....seems weird to have them both go through the loop of iso connectors, and skip it). This may make sense for Parrot installs, but doesn't seem right for the ND-G500.

Thanks again!

Certainly they do, power to the ND-G500 and power to the radio itself. With power to the amp, it produces 5v for the F500 to connect thru the cradle harness wire so no other wires are needed ( cigarette lighter adapter).

Hi again,

Sorry, I don't think i was clear enough with my question.

My point is that the G500 already reroutes the power back to the original stereo through one of the two ISO adapters. So, I'm not sure why I need/want/dont want the power also going directly to the stereo from the initial interface to the car wiring (prior to entering the G500 loop). Seems like i'm bring the same power line to it twice.

Does that makes sense? Would I just skip the part of the G500 loop that returns the power, and just use the ISO connector that returns the speaker wire?

By the way, no one I checked out locally (San Diego) had this adapter (Fry's, local stereo shops), so i ordered it online today. I hope it works out. Thanks again for your input.

Regards,

Brandon

Seems like i'm bring the same power line to it twice.

its because they are doing a "T" off between the "European factory radio connector" and "factory radio harness". Unless you have an European factory radio that use the ISO connector, then the male and female ISO connector would be useful to you. Also, you are not reroute the power back to the original stereo. Instead, you are sourcing your +12v(yellow, red) and ground from the "T", to feed it to G500. Then, the G500 feed power to F500bt.

For my case, i don't want to "steal" power from the factory harness, but instead, i bring in power directly from the battery with larger cable, in that case, i cut the yellow,red,black wire from the ISO connector and splice it onto my larger cables.

Hi,

Thanks for the reply.

I see that they are performing a "T" in the G500 wiring, and the point of this is to get power to the amp.

My main question is (assuming i'm not going to directly connect factory radio like you did), would i just leave the European plug on the G500 loop that is designed to power the factory unit "unplugged", since the harness also supplies power directly to the factory radio without the use of the G500 wiring?

I hate to assume things when it comes to wiring. Would the T in the G500 wiring work just fine to power the amp without connecting the single ISO connector back to the factory radio (using an adapter)?

I'm assuming that, to get power to the factory radio, I can either:

1) use the ISO connection from the G500 wiring to route power to the factory radio (coming off the T junction to the single ISO harness), or...

2) use the factory style radio harness on the adapter that directly connects power wires to the other factory harness which interfaces with the harness coming from the (power wires going between the two factory style harnesses used in the adapter)

But, I wouldn't use both...is that correct?

Again, sorry to sound like such a dullard, but I hate note being 100% certain with wiring!

Thanks,

Brandon

Sorry, my bad. I see what you mean now. By splicing I removed the G500's extra connector and used the QC harness for the power to the radio. You can do both, it won't hurt anything if they are wired correctly, or you can cut out either one to use just a single source of power.

I looked again at my other set of wires. The QC yellow and red wires are reversed in the connector compared to the G500 red and yellow wires. That could cause trouble. Providing always hot to the ignition/acc inputs which could kill your battery, no memory due to no power for memory circuits, and keyed hot to the memory circuits. Reversing the wires on one of the two connectors could resolve this.

Awesome.... thanks for your help. I have a wiring diagram for my factory radio, so i'm ready to jump in and break things.

Thanks again.

I would cut that red wire off from the iso connector to tap into your "+12v switch ignition", you need to include that "fuse resistor" on the red wire to protect your ND500. likewise, cut yellow wire (include fuse), and tap it into your constant 12v source. if you do this, you don't worry about loop back the power back to the iso connector that you had concern about. now cut the black wire, and connect it to ground.

Now you will identify the 4 pairs of speaker wire on your Nissan Xterra radio harness. Cut them. you immediately have 8 pair connections. (4pairs toward the radio, 4 pairs toward the speakers). identify the Pioneer 8 pairs corresponding wires, and splice them to the 8 pairs connection. you are done. any other wires are useless to you.

Awesome.... thanks for your help. I have a wiring diagram for my factory radio, so i'm ready to jump in and break things.

 

Thanks again.

You're very welcome. Good Luck!
