Despite the sauna-like temps, and with ice-water-bottles in front of my sho- fan blasting at full speed, I nearly completed the wiring (a couple things left to do). The principal goal was to secure it to the firewall to limit movement while racing, which should keep connections intact and stop cables from rubbing to bare wire. (On the yellow race jeep I could see where the battery cable had rubbed through the protective outer layer at some point, then it had been patched).
I decided to add a second jumper connection which solely handles the lights. I’ve now got most of the wiring in place in case I want to later add headlights and turn signals. I still need to add a switch to power the gauge lights and rear driving lights (in case I need them for some reason). I also didn’t think about adding a fuse for the rear lights until just now .. oops.
Ann helped me put the body into place to make sure the wire dropped under the lip of the cowl from the rollbar:
