I'm in the process of wiring my 1983 Porsche 911 SC and I'm looking for advice on the very minimal to be connected for the car to run.

I already wired the fuel pump to a relay to toggle switch as well as a starter to a relay to a momentary switch what else needs to be hooked up?

I'm thinking there needs to be power going to the ignition somehow as well as the jet tronic box?? not sure exactly how I should approach this.

any help would be grateful
