Hello I am brand new to the forum! I just bought a 1994 Delco stereo that came out of a Firebird. I am going to install it into a 1992 Camaro. I do need to buy a wiring harness for it. I have a question.... on the backside there are two receptacles for plugs. The obvious main plug, but there is also a smaller straight line where another plug would go. Is that like a special fuse or something? Also, where do I get the harness and/or fuse? I also would love to be able to wire in an aftermarket amp to add a little more volume if that is possible.

 

The 94 Pontiac radio should plug directly into your 92... they both use the same factory dash harness radio plug.

Depending on the 94 Radio you have,....... The smaller plug on the back of the 94 Pontiac radio could be the plug port used to plug in "remote" accessories such as a CD Changer. It could also be the plug port used to connect the radio to optional Steering Wheel Controls as well as the radio back-lighting circuits.
