I'm planning on running my headlights through a relay this weekend. Since you mentioned how hot the headlight switch gets with H-4's I felt mine and it was burning hot...never noticed it before. Is this an accurate diagram on how to wire the headlights through relays? I've wired realys before and it's no problem, I just want to get this done as quickly as possible with no hangups. Thanks.

I've noticed they use two seperate power wires from the battery going to each relay. Will it rob me of any power output if I run 1 power wire off the battery and split it to both relay's?
