Bare bones engine wiring diagram . . .

tekenaar · 03-22-2009

Since I've been asked a number of times, typically just after a rebuild and before engine is replaced in the car, about the minimum engine "Start/Run" wiring requirements and, seeing that a picture still appears to be "worth a thousand words", I've illustrated it in a "Windows Paint" pic for you . . .

I see someone had some free time and was missing their coloring crayons.

Quite complete. Good job.
Alternately for those whose clear resistance wire is toast, you can insert a ballast resistor from an older car (for instance 1973 Plymouth Fury III) instead of the resistance wire.
Guess how I know. ~L

What is the resistance of the wire? I know that you can find it elsewhere, but I think that it would be useful to include in the diagram

Very nice Otto! Looks like a race car wiring diagram....

Minimum for sure! It will only run until the battery dies unless you add the alternator circuitry.

Except race cars don't have a key type ignition switch.

Mine uses a SPST toggle for ignition (power to the coil) and momentary SPDT toggle for "start" and "fuel pump relay/oil pressure cut out Bypass".

Remember when all cars used to be wired that simple? Oh, maybe not...

Nope but I did read about them in History class.
