'64 Chevelle wiring

Help! Can somebody give me a very basic wiring diagram for the starter/ignition circuit for a '64 Chevelle v8? I'm restoring the car, and had to yank ALL the wiring out. I've cut out the old dash, and installed all new (state of the art) gauges. I have the wiring diagram for the car, but it isn't clear on the wiring - between the ignition switch and the starter/solenoid/coil. I'm a pretty savvy electronics tech, but I don't understand the wiring on those circuits. Why is there a GND lug on the ignition switch? What is with the resistance wire in the accessories circuit? What is the "R" terminal on the starter solenoid? I just need the basics. Surely, there is a rat rod (basic) wiring diagram out there, somewhere.

Re: '64 Chevelle wiring

If you have the wiring diagram you have all you need. The resistor wire is to drop the voltage from a full 12 volts down to about 9 volts to make your points last longer. GM used a seperate pole on the starter on points era vehicles to accomplish this. S terminal is only when cranking, I terminal is for Ignition while running.

Re: '64 Chevelle wiring

Oh forgot- the main power wire for ignition and the rest of the car comes off the big lug on the starter where the battery + wire attaches

I thought it come from the hornrelay? I remember a 64 I had where the wire from the battery to horn relay had come loose and nothing electric on the car worked.

Re: '64 Chevelle wiring

Here's a schematic, the purple wire is the start signal and feeds off the neutral safety switch, the black/pink is the resister bypass (not needed if electronic dist), and the big red cable goes to the starter lug.

That is not correct. The resistance wire at the ignition switch (brown with stripe) on the accessory circuit is the one to set a low voltage to the voltage regulator to excite the points and turn the regulator on so that the alternator will charge. The other resistance wire in in the ignition circuit of the engine harness, not the dash. The ground lug is a bulb check for the temp light on the dash of a standard Malibu and is NOT used with an SS car and a live gauge.
