Yes im 100% Sure, I've installed decks on 4 91-95 Buick regals... all the same. I just looked at the 91 Regal my mother owns as well, same deal. If you don't want a wiring harness... grab a wiring diagram from Install DR, you will also need an antenna extender and the converter since it uses the GM Smaller antenna connection.

No, the three piece isn't the upgraded radio... by three piece he means the main (where the clock displays, volume controls, etc.) the second is usually the tape deck with an empty pocket beside it, and the third being the brains under the kick of the passenger.

I have the adaptor (GM). Extender? I am going to grab a wiring harness; much easier. I just want to be sure that box under the seat is NOT the airbag/SRS mod. (etc.). Thanks guys.

 

Once again, the best way is to check for yourself. If you see an antenna wire going into the back of it, then thats the radio's brains.

 

Eureka. I was thinking the same thing. (antenna=radio). Thanks for the help RJ45 (I don't know why it took me so long to put that together). Cheers.

 

No problem, Im still a newbie... at alot of car audio related things... but I tend to help out if I do indeed know something.
