I just got a new Pioneer DEH-P4600MP and there is no remote wire (blue) one to run to my amp. The only wires that are there is the 8 multi coloured ones for the 4 speakers, a red power one, another yellow power one, and the ground. However there is one more wire that says "System Remote Control." It's a blue wire but it got a plug on the end of it so you can plug it into something. I have no idea what this wire is for. I need help on how to get the remote wire to my amp so I can hook one up. Thanks Everyone!!
