I have a wiring diagram that i dont quite understand. I'm gonna start in like a few days or so, but i dont understand how to split the green wire like it says to. I dont want to mess anything up seeing as how my green wire is comeing out of my pickup and all. should i put a little hole in the rubber of the wire and then solder a new wire to that, and from that wire to the diffrent solder point? thanks in advance!
