Can anyone give me some insight on wiring this up, i bought it used off of a member and he didnt have the directions. My questions are with the connections up front. I have the hobs switch that obviously gets a vaccum source (wheres the best place)? It already has its wires screwed to it. I have a thicker black cable with a thin whiter wire next to it im guessing the black one is constant power and white is key on? Then there is another black one im guessing thats a ground, that wire is near the relay? Then another 2 wires red and black thin ones coming out of another loom im guessing again here but i think its for the led?
