Got my sparto today. It has two wires, red and black. I am reusing the existing harness, andI assume red/red black/black, which wires from the old harness control the brake light function? Any help might prevent me from having to find a multimeter.
Well, I know that red/red/ black/black does power the brake light. I am trying to figure which wire(s) power the running light.
Not sure if I want/need full time rear light though.
Huh?? you need a better description of where these wires are and what the F you are trying to acomplish. Rear light for what? Running light? Brake light? if the answer is both, you will need 3 wires unless you have a module that drops the voltage for the running light.
