I have a 2002 ford explorer and am installing an amp and some subs in the back and have everything finished but the RMT wire. I can't find which wire it is behind the factory single CD deck. Can anyone help with which wire it is.
I looked at the diagram, and I do not see any switched power coming out of the radio, except if you had a factory mach 1 system that had a subwoofer built in. It had an amplifier in the back that was remotely turned on by the radio. It does not designate what wire did what, but the subwoofer had a:
brown/orange
lightblue/red
red/black
The brown/orange and lightblue/red are shielded, while the red/black is not, so we can assume the first two are signal wires and the red/black may be the turn on wire. I don't know if your radio would have these hanging there, even though you may not have the mach 1 system.
The only other suggestion I have is to hook the remote turn on wire to a hot in run/acc spot in the fuse box. This would turn the amp on and off everytime the key was in run or acc, but I do not know if this would matter to you or not. It would keep it from running the battery down.
