It still had street wiring left over from last year. It's under the glove box on the passenger firewall and drives everything. Dual fan motors, fuel pump, water pump, vacuum pump for power brakes, lights, you name it. Not pro looking but does the job. I have a map to remember where everything is wired in.

I used prewired relays from Pico wiring that come in sockets with color coded 14 gauge wire. Easy to work with and very high quality.

I had worked piece by piece in wiring this car up to this point, but I took time and designed the wire board on paper and built it on a workbench. I recommend the latter approach.

Since this a stock elim car, in the engine compartment
