It is a stock factory GM wire harness for the offroad lamps. I am not sure the size of the wire...I will have to check it out.
What one is the most important? The power?
The wire comes from a connector *factory* under the dash, to the left and above the break pedal. I imagine it is getting all the power from some ACC pin in there.
The lamp switch is up by the map lights...factory mounting location.
I will get some pics for you if you would like...well - when the sun comes out again.
