Ok, so I recently bought an 89' Pickup..didn't come with a headunit in it and factory harness was cut...so just got wires. I looked up a diagram because I knew it was different then my 99. I found 2 different ones, slight variations.
I tried both ones but can't get headunit to turn on..I know it works though.
Thinking a short inline somewhere? It doesn't blow RADIO/DOME or GAUGES fuses though..or CIG lighter..so I'm kinda stumped.
light blue with yellow stripe = constant power correct?
gray = switched power?(ignition ON, line is hot)?
Black = ground?
Those wires should let headunit turn on at least..but it doesn't.
Like I said I know the HEADUNIT ISN'T FRIED.
I'd run it with my meter and find what's what but I left it in my gang box at work...and I wanna get it in this weekend
