I bought my 84 trans am with no radio installed in it and the only wires i can find are one blue plug with 4 wires and one small white plug with 2 wires.

neither the factory or aftermarket radio i installed are working, the fuse is good

the factory radio and the wire adapter both have spots for extra plugs, so is my car missing some extra wires or are these all there should be

I just finished sorting out my '85. Wiring should be the same.
You're missing two plugs.
It looks like you have the rear speakers only and the main power.
I think if you provide a ground to the black wire on the radio it will play.

The ones your missing should branch out from a bundle that feeds into the console from under the carpet like this.


Here is the wiring list.
