Default C3 Starter Switch Panel Wiring Questions

Hey all,

So I recently acquired a VERY ragged-out 77. By the looks of things it appears the guy I got from had turned it into a very redneck race car at some point in its life. The whole car is a mish-mash of different year parts, it's been hacked up, and the body is super rough. When I got it, it had a very amateur ignition switch and push-start button rigged up with wire nuts for all connections. I say all this to explain why I'm putting a starter switch panel like the one below in the car. Ordinarily it would be super tacky, but this car is so far beyond a tasteful restoration that I just want to get it running and driving for the time being.

My question is, how exactly should I wire the panel up? The main power wires under the dash have all been hacked up and spliced into. I tore all the "new" wiring out and plan on wiring everything straight to this panel, mounted to the center shift console. I've attached a diagram of the various switches and wires, but I'm not sure exactly where to start, and I don't want to start splicing and attaching wires before I know if it'll work.

The plan is to use the main toggle switch on the left for the Ignition; Starter button to start; and then maybe the first toggle for ACC power.

Also, should I put the included relay on the starter switch? I know it's an older car, but I'm not sure if it's required or not.

Any help would be appreciated. I've included a diagram of the switch layout for help.




This diagram is on the Amazon listing.




This is my best guess about how to start.

Here's a clean diagram to work with.

First of all there are two ignitions-

1) ACC and Ignition ON - but off during start

2) Ignition ON during start- off during acc

So when you start the car- the gauges/coil are on- but not the radio or wipers.

You'll also have to interface the starter lock out for the clutch or neutral safety switch for the trans....otherwise - pushing the button the car is going to take the garage/you or anything in front of it out...

I'd have a relay for EACH circuit/switch- looking at those switches- if you pull more than 15-20 amps won't take long for them to be toast.

Mines a little more elaborate ... also see the OEM wire reference
