I need some help on wire routing. I made this Hornlite from multiple pieces. It was not complete when I got it. First one I've delt with. The best I can figure is the light needs a positive wire and the horn needs a positive and a negative wire. The light gets its ground from the horn ground traveling through the body housing. Light works and horn works. My question is, if this is correct, is there two holes drilled through the fenders for the horn positive and negative wire? Or, do I some how get the two horn wires through the body over to the light section and then down through the bolt hole? That way I would need only one hol e in the fender. Could use some clairity on this. Thanks!
