What kind of wiring system does a 1964 Pontiac GTO have?
The wiring systems of the 1964– 1974 Pontiac GTOs are probably closer in complexity to a Model T Ford than anything currently in showrooms. While that may be true, wiring systems are still a point of fear and loathing among many restorers of Pontiac GTOs and other muscle car era machines. The truth is, it really isn’t that bad if you plan ahead.
What causes a wire to come out of a GTO?
Sometimes, it is a simple fix, as when a wire was pulled and stretched enough that it came out of the back side of a plug-in connector. Perhaps a plastic wire insulator cracked with age and exposed a bare wire to some bare metal and a short was caused. Keep an eye out for obvious problems like that.
Do you need ground straps on a 1974 GTO?
Unibody cars do not have this level of reliance on ground straps like a conventional body-on-frame design, but even the stub-framed 1974 GTOs need them more than a modern car. A wiring diagram from your shop manual lists the number of grounding points and their locations.
Where are the grounding points on a GTO?
A wiring diagram from your shop manual lists the number of grounding points and their locations. If they are missing or no longer functional, correct replacements are available. Once the grounds have been attended to, it is time to move on to the other connections in the car.

What to do if your GTO wiring is not complete?
Use a multi-tester to make sure that all the wiring is still func¬tional and replace the wiring that does not complete a circuit. Simply connect the multi-tester’s probes to the connections to see if current passes though the wiring. If it does, the gauge on the face of the multi-tester moves to show the current flow.
Why are the jumper cables on my GTO not working?
Of all the electrical connections on your GTO, chances are that the battery cables and terminals have seen more use and abuse than any other part that carries current. Often, the terminals have been overtight¬ened and distorted. Also, jumper cables have gouged them and battery acid has cor¬roded them.
What kind of battery cable do I need for GTO?
If they need to be replaced, make sure that you get cables of sufficient gauge thickness; it is more important than how they look, as cables that are too thin can cause too much resistance and can heat up. Unless you are competing in concours judging, pass on 6-gauge battery cables and reproduction tar-top batteries.
