This evening I only worked for a little bit. I made an extension for the cable-clamp for the heater control, this puts the cable in-line with the arm of the selector box. I use an AN970 washer to spread out the load to minimize and flexing of the firewall.
I also made the buss bar that connect the battery contactor to the starter contactor. I used two strips of 0.063 copper and soldered them together prior to drilling.
