Fuel Gauge, Lighter, Interior Dome Light Issue

[aristoman]

Funny story. I installed a new radio to replace the father inlaws radio. Went for a ride and the brake lights weren't working along with the fuel gauge and dome light. There is a connector behind the rear seat that was "jacked" up, after fixing it, the brake lights work, then the dome and fuel gauge are working now. Almost bought a sending unit.
