I've been wanting to do the 4 headlight high relay on my 93 for quite some time, but never got around to it.

Questions;
1. About where do the relays mount?

2. The 2 orange wires hook straight to the battery, correct? Black is ground of course. The 2 other plugs, (activation wires for the relays from the headlight switch I assume), hook into my truck harness where? (I've never seen that style plug-in in my truck is why I ask)

3. I don't care for fuses in the headlight circuit myself, Is there a way you could replace the fuses with circuit breakers? If not, if one fuse would happen to blow for whatever reason, I would lose both headlights, correct? Meaning both right and left side, low or high beams, depending on which fuse blew.
