Hey. Wiring up my head unit, and the asshat who had the car before me cut the harness, so I just have a jumble of wires. I seem to have gotten most of them, but does anyone know what color wire does what in the stock 87 Firebird?

Actually, I did pretty good with guesswork. The headunit comes on (and goes off!), and will play out of the rear speakers (but, I wired them into the front speaker wires on the head unit, apparently). Really, I guess I just need to know what the front speaker wire colors are.

It's entirely possible I don't have front speakers, too. I really don't know, and I started this project kinda late, and it's now dark out. Rather than trying to get in there to see what I have, I figured checking the wires would be easier.

 

Don't know if they are the same, but for a Camaro
violet/black= right rear neg
violet=right rear pos
green/black=left rear neg
green= pos
white/black=left front neg
white=left pos
gray/black=right front neg
gray= right f pos
blue= antenna
red= switched power
orange/white=dimmer
black ground
yellow= constant battery power

Hope this helps

 

Some of the colors are used twice for totally different things. Be sure to use a volt/ohm meter to check the wires before connecting them.

orange= +12 constant
black= ground
yellow= +12 switched
brown= parking lights
gray= dimmer
pink= power antenna
gray= front left -
tan= front left +
lt green= front right +
dk green= front right -
brown= rear left +
yellow= rear left -
dk blue= rear right +
lt blue= rear right -

 

Thanks. I'll have to pull it out one day and check it all. Right now, i'm just leaving it as it is. I have a radio, i'm happy at the moment. Gotta wait for a nice day when I get motivated to pull everything out again.
