New Wiring for RalphVee

I'm about 99% finished with the new wiring on the FV. I had a couple electrical issues at the last event, including what I think was a fried + wire to the coil, and a bum ignition switch. So with Mr As help, we drew up a wiring schematic last Saturday, and I searched around the valley for the various parts and pieces I needed.

I found a simple junction box and a 8 port terminal strip to help separate all the individual circuits, instead of just running them off the main disconnect or ignition switch. The seven circuits are:

Brake Light
Rain Light/Mister
Wideband Controller/Gauge

New junction box, new push button starter, and new 50amp ignition switch

I also made a new big power wire running from the main disconnect to the + side of the starter. the old one was just short enough to where it had to run too close to the headers. Having it longer means I can run it farther back, before turning it around the back of the car, avoiding the headers altogether.

I took my time over the past couple evenings running new wires, crimping new connectors, and routing everything through the chassis properly. I even bunched wires together and ran them inside some split plastic loom protector sleeves.

All new wiring and looms running to the back of the car

I also took the time to add a circuit for a brake light. I was one of the few cars in the race group without a brake light (being a formula car) so I figured I would add one while I was going through all this effort. I fabbed up a bracket that comes off the brake balance bar and works on a generic brake switch I grabbed from NAPA.

New brake light mounted up on the roll bar. The light mounted PERFECTLY to the existing two bolts that hold the head rest. Amazing.

Now all I need to do is clean up the giant mess in the garage! Amazing how many tools it takes to do a job like this.
