Does any body know if there is a special ac delco radio that goes with the 88 gta digi dash i do have the performance sound option. The reason im asking this is cause i went to hook up my stock 89 gta ac delco radio an the connectors for them are totally different i want a direct plug in radio so i dont have to cut an splice into the factory connector does any body know where i can find one ???

 

That was right around the time connectors changed. I assume that's your situations based on "connectors for them are totally different."

AC Delco and others sell adapter harnesses.
