Does anyone have the pin out for a 1994 Firebird with a 10 speaker system? Everything I look at is different and none of them match what is in my car. It is a 20 pin block an it has 16 wires running into it. I want to replace my POS stock head unit and keep the speakers and steering wheel controls (have a PAC coming as well) in the car now, but the wiring has me worried.
