Typical Delco Loc radio, NOT Delco Loc 2. Bought it off of ebay a couple of years ago. Wiring all the same as my 88 GTA EXCEPT the data input connection. Mine has the orange and blue/black. This one has two dark green and a purple. Part number 16087090 and then 89AMCC.

nope

I finally chased it down to a 91 Bonneville SSE

Spoke to the guy on the second link and he was helpful, told me also that a boneville radio is different than a gta radios, the plugs are different colors for the steering wheel control, so they cant be interchanged. ????
