Help. Im making my first hot rod.

[Larald]

I took out the 1995 5.7 and I'm going old school. A classic 1970 402ci big block. No computer or ABS. I'm making a wiring harness. What wires do I need? I drive a 1997 so that helps. This is my first build.

To make the engine run. One hot wire to the plus side of the coil.

if you are using GM HEI just a +wire from the ignition switch to the distributor , if you are using external coil + to + coil from i switch . wire from i switch to starter solenoid. depends on alternator how thats wired, I would go with single wire so all it needs is battery connection then you need to do the gauges and tach

Ya, I would agree with that. Power to the coil is always good.

 

If he going to go that far though, then he will need some sort of engine ground wire too I guess. 

 

That opens up a whole can of worms though - because at that point he will need to get some spark plug wires.

 

And battery cables too for that matter.

, early GM HEIs, the 1s with the big dist cap have more spark than anything you can buy
