fiction520 Posted October 15, 2008 Report Share Posted October 15, 2008 oh ok, I missed where you said you have a gti. Many volkwagens have no accessory wire behind the radio, you need to tap one near the ignition. Whatever wire you tapped thinking it was an acc wire is a constant wire and that's why it won't shut off. I'm sure if you search google you find a suitable wire to tap.

HiFiSi Posted October 15, 2008 Report Share Posted October 15, 2008 Does the cigarette lighter/power port only work when the car is on? If so, that is a suitable place to tap into to get a switched power source for the red wire. Quote Link to post Share on other sites
fiction520 Posted October 15, 2008 Report Share Posted October 15, 2008 That can work but I've seen it pop fuses a lot with regular hu's. I'd imagine the avic would draw a bigger current. The ignition is always a good source, I forgot to mention you definitely need to fuse it if you tap it there. Quote Link to post Share on other sites
nikefans Posted October 15, 2008 Author Report Share Posted October 15, 2008 tap it to the ignition ... that's way too technical for me ... Quote Link to post Share on other sites
Yettavr6 Posted October 15, 2008 Report Share Posted October 15, 2008 You're car doesnt have a switched 12v in the harness, not sure why the harness you bought has one. Most people tap into a fuse in the fuse box which turns off with the ignition (e.g. wipers). Just curious, did you connect your speed sensing wire, reverse wire, etc? If not, you should look into buying a product called CR2-VW from PAC. It will replace the other harness that you bought (maybe you can return that one?) and will give you EVERYTHING that you need, including the ACC, illumination, parking brake, reverse, and speed pulse. Enfig.com sells it for about $70. EDIT I meant C2R-VW. Heres the link: http://enfigcarstereo.com/shopsite_sc/s ... 2R_VW.html It will make everything super simple, and it has a plug to directly connect the SWI-CAN if you want to retain your steering wheel controls Quote Link to post Share on other sites

So if i bought the C2R-VW ... i can just connect everything color to color with somewhere that i can connect the ACC wire and the orange wire that i dont know where to connect? does it come with instructions?

Yettavr6 Posted October 16, 2008 Report Share Posted October 16, 2008 Actually the instructions are here: http://enfigcarstereo.com/shopsite_sc/s ... CTIONS.pdf I dont think the reverse, speed pulse, illumination, etc are color coded the same as the pioneer, but they are labeled so its easy enough to match up. The orange wire that you couldnt hook up is the illumination wire (which will dim the screen when your lights are turned on), so you will have that, along with the red ACC wire with the C2R-VW.

nikefans Posted October 16, 2008 Author Report Share Posted October 16, 2008 what are the other 2 wire for steerying wheel control? SWI-CAN and what ?? are they both plug and play easy .. do they come with instructions? is my bluetooth button going to work with the headunit too ? Quote Link to post Share on other sites
Yettavr6 Posted October 16, 2008 Report Share Posted October 16, 2008 The small plug is to connect to the SWI-CAN and the other set of wires is not used. I believe PAC uses them to upgrade the firmware if one becomes available. For the SWI-CAN, you will also need the SWI-PS which connects directly to the Pioneer. So it would go: Factory Harness > C2R-VW > SWI-CAN > SWI-PS > F90BT All plug and play as far as i know. Here are the instructions for the SWI: http://www.pac-audio.com/instructions/s ... 20rev2.pdf In there where it shows "Chrysler, Dodge, Jeep usign C2R-CHRY", that also applies to VW using the C2R-VW.

RYVAL Posted October 16, 2008 Report Share Posted October 16, 2008 alrighty, here's a heads up for you... and will solve all the confusion... VWs don't have switched accessorys. So the Red wire is working perfectly... according to VW. What you'll need to do is buy an external switch and manually turn on the deck every time you turn on the car. It's a shitty way of doing it but sorry about your VW. oh, and yes, that is a terrible tape and connection job.. just because the ends of the harnesses are stripped back 1/4" doesn't mean that you can't use more of the wire. Use some wire strippers to strip back around a full 1" to 1 1/2" per side to twist together. Use some HIGH QUALITY 3M temflex tape to wrap the connections. Forget the term "less is more" when taping. Get a good length and wrap it tightly. you won't need heat shrink if you have good enough electrical tape. Quote Link to post Share on other sites
Yettavr6 Posted October 16, 2008 Report Share Posted October 16, 2008 Sorry but the switch idea is a terrible idea. The adapter I posted will work perfectly. And it's not just a VW thing, almost all newer cars control the radio via the CAN bus. In fact GM's were one of the first cars to not have an ACC wire at the HU.

fiction520 Posted October 16, 2008 Report Share Posted October 16, 2008 LOL at the toggle switch idea. Use those harnesses yetta suggested, get switched power from the ignition like I suggested but don't install a toggle switch. Quote Link to post Share on other sites
