I have looked all over for info on where to find this wire. I got a schematic from the dealer that said it's Dk. Grn/ Wht @ the PCM in the Engine bay just back from the radiator. Anyone got more accurate info; because this JVC POS EXAD is about to get tossed in lieu of a Pioneer.

The problem is that although i'm 99% positive the wire is the right one... the JVC piece will not calibrate properly. Got the e-brake wire on a switch. Got the right reverse wire. The install manual says all 3 need to be connected. Did that. And although it picks up 7 satellites and is more accurate than the actual Speedometer in the car, it still tells me I'm in Washington.


I'm pullin my hair out on this one. I also have a 06 Caravan coming in for the same thing and could not locate the BCM. Somebody please give me some accurate information so i can stop going gray....er.

Thanks in advance.
