I got a new Pioneer head unity and install kit from Crutchfield, along with their mastersheet for my wife's 2003 Dodge Grand Caravan with the Infinity sound system. Was wondering if anyone in this forum has replaced the factory radio with an aftermarket and still used the Infinity amps in this forum. Crutchfield has instructions, but not 100% clear on a few things. I also got the E-5000 relay from Crutchfield, which the instructions say to use. Just wondering about where the gray / dark green wire is. The instruction show where to find the dark green / gray wire. It'll probably be obvious once I'm in it, just trying to find out as much info as possible before I get elbow deep into it being the wife's van and all. Thanks.

Call Crutchfield tech support and ask them. They are VERY good at telling you how to hook up their harnesses.
