The red ring wire and multiplug wire have no power going to them. I've tried it with ignition on, lights on, heater on etc and nothing. Maybe it was for a heated from screen on something??? The green wire circled in the second picture is an ignition live but not permanent. I'm thinking maybe fuel or temperature. The fuel guage never worked so maybe that's the live for the fuel. Idk no fuel tank in as it leaks so need a new one. I hate fault finding electrickery.
