    1979 Trans Am Wiring Diagram

    Posted by Brian on 13th Jul 2019

    Bought a TA that had been seriously abused. Looked like the previous owner had pull the dash out and just left wires hanging all over the place. With this color coded diagram I was able to identify everything and got all the gauges and lights working. Also helped be get everything grounded properly so the the rpm hand does not sweep back and forth with the windshield wipers anymore

    This wiring diagram is the best I've seen or used. the laminated sheets are easy to clean, store, and use. I have purchased several for the cars I have worked on over the past few years and have recommended your company to several builders in my area. always great products.
