    On a stright blade three plug system, I know there is a wire in the 11 pin light harness that tells the module the plow is hooked up. Which wire is it? Does it go to ground or to power? I am looking at a plow and the light harness is shot. I can hook into plow control and the main power. I just want to be able to operate plow to see how it works, so I need to trick the isolation module on my truck to think there is a plow hooked up. I don't care about the lights actually working.

    I am far from my shop and my fisher books.

    Ground the black/orange wire at the ISO based on what you're doing.
