I am trying to install a basic aftermarket stereo into my 91 base V8. Everything seems to be connecting correctly, but I have found there are 2 ground wires coming from the car's wiring (one black, one red.) Not sure if I join those 2 and then connect into the new radio ground wire, or if one gets capped and left off.
