I got a 03 mustang gt and i wanted to buy a pioneer avic z1 but crutchfield says that i need to buy a aftermarket amplifier but i been looking and i see that there are harness like the metra 70-5519 that lets me connect directly to the factory amplifier. will this work? will it give same sound quality? will i have to buy anything else?

thanks in advance

I take it you have the mach system in there? If so then that harness will allow you to retain the mach system while replacing the radio. You will also need the dash kit for the car. Part number is 95-5026. If you're going to do this one yourself here's the wiring stuff you'll need to make the gps the most accurate.

Reverse Light black/pink + 26 pin plug, pin 20 at GEM
Notes: The GEM (Generic Electronic Module) is located above the driver kick panel.

Speed Sense white/orange pin 68 at PCM
Notes: The PCM (Powertrain Control Module) is located behind the passenger kick panel.


merry xmas

and i change these wires on the harness? do you know if these is a guide with fotos or at leasr explaining hot to do the whole process?

To my knowledge there isn't a specific guide for what you're doing.

what would be the harness that you would recommend me to buy?

The harness you mentioned in the first post. Then get the dash kit I mentioned in the second post.

and when you told me to reverse the wires do i really have to do this to work? and those wires are from the harness or from the car? sorry for making so many questions but i dont want to screw up so im trying to find the steps on how to do it

The reverse input wire you don't need unless you're going to hook up a backup camera. The speed sensor wire you want to hook up it will make the navigation a bit more accurate plus it will allow you to use all of the vehicle dynamics displays. Here's how they break down

Reverse light. The wire is black with a pink stripe. It's at pin 20 of a 26 pin harness at the gem. The gem is the large box above the drivers kick panel.

Speed sense. The wire is white with an orange stripe. It's at pin 68 of the pcm. The pcm is behind the passenger kick panel.

i see you really know you stuff and i really appreciate your help. Im not going to need the reverse wire i don't want the camera but the speed sense sounds like a good idea. so for example for the speed sensor i connect the harness to the orange strip thats on the pcm. one more question the harness is just plugging in the head unit and into the car or i have to cut wires?

thank you

You'll have to splice the wires from the 70-5519 to the wires that come iwth the avic. It's not hard, just match the wire colors and either solder and tape, or butt connect them. If you do solder and tape make sure you use good quality tape ie 3m super 33+. Best electrical tape in the world. in my opinion anyway.

Here is a great how-to for replacing the head unit on the mach system. Remember you will need bass blockers for your tweeters.

I know the link is for an 01, but I believe it will work for all the mach systems up until '04, just be aware that it might be slightly different.

but doesn't this model already have the 2 crossovers built in? if it does i dont need the bass blockers do i?

With mine (an 01) I didn't install the bass blockers and just used the Metra Harness, the tweeters were constantly popping. I went and picked up some bass blockers, and that made all the difference.

I may be wrong, but I believe the tweeter's amp is in the head unit (with the crossovers for them)

I had a '94 with the Mach system and the amp for the tweeters in that car was mounted below the 2 decks (the '94 had two single din slots) and was not part of the head unit.

ive been browse through the internet and i found this

metra PR01-1770

it says that it is a harness for pioneer to ford, would this work for me? i dont feel like splicing my pioneer wires.

Nope That will only work for normal pioneer radios. The avics use a slightly different plug. It's not a big deal to splice wires. Just match up the colors.

Hey peoples, I've been reading all these posts about installing the z1 into a mustang with the mach 460. Everyone says to get the metra and the bass blockers. But... my last 2 cars were mustangs with the mach 460 (a 97 and a 2000) and for both of them I used the peripheral SVEN2(line output converter) and the SVHFD3(ford add a head for the Mach460) and I never had a problem with my tweeters popping. You can get both of those units on eBay for 50 bux shipped now.

Thats the route I'mma go with when I buy the z1 after xmas. I'll be sure to let everyone know how it goes with pictures and such :).

If someone else has tried this approach and found that it doesn't work for some reason, please don't hesitate to bust my bubble. I'd rather find out now then later.

Im very new to this forum, but for what its worth I installed the z1 in my '04 cobra and have had no problems with any popping from the tweeters.
