Any one have the radio wiring diagram for the 92 5.0 lx? I found http://www.installdr.com/Harnesses/Ford-Wiring.pdf
But it doesn't seem to help. Im mainly just looking for the ground, ignition on, and constant power, to test my new head unit before working on my wiring for my new Subs.

 

these may not be exact

1992-93 Ford Mustang Stereo Wiring
Constant 12V+ Green/Yellow
Switched 12V+ Yellow/Black
Ground Chassis
Illumination Blue/Red
Dimmer n/a
Antenna Trigger Orange/Blue
Antenna Right Front
Front Speakers 5 1/4" Doors
Left Front (+) Orange/Green
Left Front (-) Light Blue/White
Right Front (+) White/Green
Right Front (-) Green/Orange
Rear Speakers 5" x 7" Side Panels
Left Rear (+) Pink/Green
Left Rear (-) Pink/Blue
Right Rear (+) Pink/Blue
Right Rear (-) Green/Orange

 

you will want to test those wire colors with a volt meter or test light. If you don't have one, they are $10 at the store and should be in any tool box.

 

Thank you. Now I'm going to have to figure to fish out my broken RCA plug pins from the RCA connections on my amp. That's what I get for moving it around without unplugging everything.
