So when the truck is off so in the radar and when I turn the truck on its on. I also used it for the power wire for my gauges and I also ran a wire from the trailer running lights up to my gauges so the backlight comes only when the lights are on.
I have not yet been under the truck to look at the loom (or the wires in it) but am planning on it as soon as I get my on board compressor and airbags.
My question is....Is it obvious which wire it is? What color is it? Or is it larger than the other wires in the loom thus making it obvious as to which one it is?
