I have this plug that I don't know what it does or belongs to? Does anyone know? Thanks.

 

Looks like the wires that control steering wheel controls. They plug into the opposite side of the main plug on the rear of the radio.

 

Well that's weird cause my car doesn't have steering wheel controls, do you know if all third gens came with this even though the steering wheel doesn't have them?

 

I may be wrong. I am just saying thats what it kind of looks like.

My IROC did not have that plug, but it also has the older style 4-plug type deal in it, in 89 they swapped over to that style. Maybe someone else will chime in on the subject.

 

maybe this will help ya?:

 

Well I'm at work and i can't see what you have posted so when I get back to the Tent I'll check it out. Thanks.

 

Looks like thats the diagram for the main plug. Even so, a useful diagram.

 

Ahh, i think I've seen that diagram around here a few times. I think when i get to install the radio I'm just going to leave that plug out of it cause it seems its useless in my case.

 

i saw on another thread that the orange wire u have there is your constant 12 v
