This is the general idea of the rewire: Two mil-spec Deutsch connectors poking thru the firewall. ECU, relays, bus-bars, etc will all be mounted on a 12" square alum panel. The panel is secure with two Dzuz 1/4 turn screws on tabs I'm welding to the inside of the glove box. The back of the alum panel will be secured similarly. The idea is to make it as accessible as possible with the ability to pull the whole panel out and intact with quick disconnects and keep it up and out of reach of kicking feet in the passenger area when installed.
