Hooking AVIC 1 up to the PCM.

I have had an AVIC for almost a year, and the vehicle dynamics wire has NOT been hooked up to the PCM. The wire(pink) is hooked to the AVIC, and all ready to go into the PCM, but, I have no idea where or how to hook up. My car is getting worked upon so i have the ability at the moment to have it on a lift. I guess there are "pin #'s" on a PCM, and the pink wire goes into a "pin #"? Can someone please give me some help in hooking this up.

Thanx

Jim

Hope this helps...

Is the pink the speed sensor wire ?? if so here you go.

After some, disassemble of the dash of course with the service Manual in hand! I found the right green/white wire. It goes to the plug on the back of the instrument cluster. Actually there are two green/whites, one is for the Oil Temp the other is the speed sensor wire.

After unplugging the connector from the cluster you will find two green/white stripe wires, you will want the Green/white (A7-circuit 817) with a Tan/white (A6-circuit 33) above it and a black (A8-circuit 150 ) below it..The other green/white (A10-circuit 357) oil temp has a blank and a gray on each side.

pin..wire
A5 Blank….
A6…Tan/White
A7 Speed Sensor…Green/White
A8…Black
A9 Blank
A10 Oil Temp…Green/White
A11…Gray

Step 9c shows the plug...I did not have to remove the cluster to reach it just pull it forward..

thank you.

Could I also tap into this Green wire with white stripe at the PCM, rather then taking the dash apart?

don't bother taking the dash apart. just remove the knee bolster and find the bundle of wires, use a wire tap and try one of the two green/white wires, turn on HU and see if it recognizes the signal, if yes you're done, if no disconnect wiretap and switch it to the other green/white wire, put the knee bolster back on and go for a drive.

i also have avic-n1 btw but i'm not running with the speed sensor wire hooked up.

Yes you can, I just did not want to put a hole in the firewall. cmeflyby sounds like he has an easy way to get at the wire, I just was not sure so I went to the plug. As much electronics as is in a C5 I did not want to take the chance of shorting something out.

I was wondeing about this.

does the stock head unit work off a speed sensor wire as well? It has that volume thing that turns up the stereo louder as you go faster. if yes, then would the green wire with the white stripe on the back of the stock stereo harness be the speed sensor wire?
