At some point the original radio pigtail was cut off my car, and I'm looking to replace it. I'm not totally sure which one is correct for my car though - it's an 88 GTA, that originally had the steering wheel radio controls, and factory amp and sail panel subs. Do the steering wheel controls have a separate plug? My original radio is long gone, so I'm not sure. I found one at modern day muscle, can anyone confirm if this is the right one?

That's the 90-later car plug. You want the earlier 3 piece style... Like so...

Awesome, thanks! So I take it the steering wheel control is a separate add-on plug then? I do seem to remember a small unused plug behind the radio that hadn't been cut.
