I need the wire colors and orientation on the plug that goes in the back of the radio for the steering wheel controls on an 89 Trans Am. It is a 5 pin plug with 2 wires, one on each side. the rectangle plug has a guide sticking out on each end of one side and I need to know which wire goes on which end. Can anyone help, I have manuals for other years but 89 is a different 1 year only deal. THANKS !!!

 

Thanks to Camero?? I got the answer I needed, the black/blue tracer goes on the outside edge of plug, the orange goes to the inside. THANKS !!
