I just bought a nice 89 GTA.. the guy pulled his headunit, and gave me the GTA stock one. I spliced the harnesses back in, but am missing ONE... the one that the orange and ?brown? wires go into... and my steering wheel WONT unlock the headunit.. PLEASE HELP I NEED MUSIC AND HAVE NO MONEY!!!!!!



No, seriously, help me!

 

There's a separate plug for the orange and brown. The orange is either battery or ignition, and the brown I believe is the dash light dimmer.

Well, why wont the headunit unlock when I push mute?!?! Is there something else I need to do?? Check?? HELP!!!!!!!!!!!

 

PLEASE HELP ME!

Forget about unlocking...the thing shouldn't even turn on at all unless that orange wire's hooked up.

 

Yeah, make sure all wires are hooked up. Once everything is hooked up, try unlocking the deck with the mute button. If that doesnt do anything, double check and make sure all your wires a re-spliced correctly. If everyhting is hooked up right and it still doesnt work, the steering wheel controls or just the mute button might be messed up. Try cleaning the contacts out underneath the button if possible or use a can of contact cleaner on it.

There can be only one!!

 

OK... So I gotta hook them all up... the ONE opening left in the rear of the head unit has TWO pins in it (for TWO wires) they are numbered one and five... can someone tell me which wire goes where? PLEASE?!?!

Thanks guys!

 

Shouldn't that be the one for the 2 wire plug with the Orange and brown wires you were wondering about? The other 3 harness sections all have multiple wires.

The last harness only has TWO wires for it.. I dont have ther harness itself, but the two pins in the rear of the radio, and the two wires that are supposed to go into it... which goes where?!

Thanks guys...

 

Just go back to the junkyard and get that harness and do it right.

One of those wires is for illumination (brown), and the other is for constant power (orange). You won't do any damage if you hook them up backward by mistake.

If the backlighting is constantly on, and the radio will only turn on if you switch on the parking lights first....then you have the two wires backward.

 

look at this link it explains how the system works. http://www.geocities.com/motorcity/1500/swc1.htm

the orange wire is a 5 volt data path from the controller and is NOT for lumination. I think orange should go to pin 5 the other is black and is ground (look through the holes on the side of the radio you should see the wires inside) PAC makes a module for the interface and may have addtional info on the web site
