I'm working on installing the wiring harness for my heated windscreen. It's for a RRC but using a Defender harness from Mobile Centre
. Nice looking harness... too bad I have to modify to fit. I'm stuck with not knowing where one wire should go from the switch. It's the negative side of the light. Does it just get grounded?
It's a switch out of a 94 RRC. The switch wires go to terminals 1 & 4 on the timer relay and the light goes to 87 on the 70A relay and that's where I'm stuck with the one other wire off the light.
