The connectors I ordered came in today so I decided to draw up a schematic for the 4-hi mod with my fuse & relay distribution block. I don't like using diodes, an extra relay works better IMO. Anyway, take a look and see what you think. Keep in mind, I drew this up so I can just disconnect a couple harnesses and the primary wires to remove it for repairs/modifications at any time.
Edit: BTW according to the GM manual
@hatzie posted the low beams are fed with a size .8 wire and the highs are fed with a size 1. According to my metric to AWG conversion chart, a .8 wire is a little bigger than an 18GA and a 1 is somewhere a little smaller than a 16GA. I'm thinking about going with 14GA to the lights since I have a bunch of it. At least this time, I'm trying to plan ahead, LOL.
