Hey guys.

When i hooked my Sony Xplod head unit into my car last year, the power supply for the radio was no where to be found, so i just hooked it right into the fuse box. After having to fix my gauges i realized that the genius that hooeked them up, hooked them into the sterio power supply. I fixed that and now have all of the wires open for the sterio and want to hook it up right. Problem is that i dont remember what the hell goes where, and for some stupid reason i didnt get a smart harness. I still have the factory harness that was on the car that we cut off. Would it be easier to figure out which wires connect to which, or to rehook up the factor harness, matching the colors and then just get a smart harness?

Also, since ill prolly atleast try to just match wires, can i get a chart or something that shows which colors are what? A chart for a sony explod head unit would be great too if anyone has it! Thanks.

BTW: 1992 Camaro RS

 

This from a 88, your 92 should be the same colors.

 

Power for 99% of head units is
Black=Ground
Red=Switched 12v
Yellow=Constant 12v
Blue=amp turn on or power annt

 

88Trans, you were close, but they changed the wiring harness in 89

the one he needs is this:

 

I was about to say that, But I thought they changed them in 90?

 

The one I posted is exactly what I had in my 89 RS and my current 97 Grand Prix. Made the deck swap pretty quick

 

ya i have a 86 and a 89, and I know the wire harness is the same, with the white black and blue plugs, and it uses the same wireharness adapter for aftermarket headunits. idk

 

hey, thanks guys u just saved me alot of time...this web site is alwsome!!!! i didnt buy the kit so im just tryin to match colors (just like the original poster)...

 

can anybody tell me what the "lights on" input is for? my 92 RS has a pioneer deck in it and whenever the key is turned on the parking lights come on. Also when the key is off and you turn the parking lights on the radio comes on. I found the grey wire was hooked to the yellow wire from the stereo. Any thoughts?

FYI the brown dimmer light is not hooked up at all.

 

I unhooked the grey wire and now the parking lights come on when they are supposed to. Just wondering if I just leave those grey and brown wires alone since there is no hook up to the pioneer deck for them.

 

The grey wire is for the instrument panel light circuit. ON with parking or headlights. Brown dims the display(clock/station)

 

cool thanks. I just capped off the grey wire and the brown wire from the factory harness. The radio lights up whenever its turned on and has no wire hook up for any lights. I hate it when somebody hooks up aftermarket stereos and doesn't know what they're doing.
