stereo wiring harness question

mr2pwner · 10-25-2009, 04:04 PM

Car is a 93 n/a, wondering which wire from the aftermarket stereo head unit hooks to the "Pin 1 Blue/White Amp Turn On" on the 14 pin wiring harness.

I have this harness, but it does not have the RCA plugs, only the white/black/green/purple wires.

well, black is going to be ground, red to power and its usually a blue wire. i would guess the darker blue one.

Red is a key hot,
Yellow is a constant 12v all the time,
Black is ground,
Blue is usually antenna,
Other blue might be for remote?

no, the blue/white wire powers on the stock speaker amps, i know what all the other wires go to black, red, yellow, etc. i'm assuming that the blue/white wire hooks to the red accessory along with the red wire? something has to tell the amps to turn on when the car/stereo is turned on or else the stock amps will drain the battery.

i want to run my two 6.5" boxes behind the seat and the entire stock system at the same time, all factory speakers and amps were fully functional before the stock head unit was removed (radio worked, nothing else).

anyone? is the wire even necessary? no one has ever used the stock speaker/amp system before? sorry for the double post but i really need to get my dash back together. any help would be greatly appreciated.
