Well I found out the guy has the dash harness with the bulkhead that goes into the firewall! That appears to be the most expensive part of the system.

Year One's website says it includes wiring for headlight, wiper/washer, flasher, turn signal, horn and ignition switches, panel gauges/lights and heater. Also includes the fuse block and bulkhead disconnect.

It looks like the engine compartment harness will be about $142 and the rear light harness is about $93. I won't have a factory fuse holder though, maybe a universal deal will work.
I'm terrible at wiring so I need to do this car the easiest way possible with the harnesses, starter relay, aftermarket ignition etc.

Maybe a stand alone type ignition and distributor will make things easier? I remember something mentioned here about the Firecore50 distibutor and ignition.
