Help with dash Wiring Harness schematic
I am wiring three sets of lights (roof spots, bumper floods, bottom of bumper fogs). I would like to use three of the switches on the left of the dash/steering wheel (US). One is already wired for the bottom of bumper fog lights (although I cannot get power to them and am rewiring). The other two are harnesses were connected to non-functional fake switches (apparently I didn't get those options). Is anyone aware of a schematic that says what each wire on each harness does?

Just tested all the connections on the three harnesses. They are all wired a bit differently. The top two have a hot wire from the ignition on #2. The fourth (bottom) harness is wired directly to the battery on #1, and to the ignition on #4. Looks like I've got some creative wiring to do.

That's just about my plan ... except rather than Cruise Control switches, I've found two more Front Fog Light switches (and pigtails) on eBay. I'll use the format of the already installed light switch and try to replicate it in the two new switches. I'm seeing some trial-and-error in my future to get it right, but that's half the fun.

What I did is buy 5 cruise control switches, and wired them all up together in one go (daisy chain the 12v, ground, and dash light wires, with a bundle of individual swifcb leads coming out) so you don't have to do it again and are ready for whatever accessories you add later. Small enamel paint brush and white paint to label the covers. Next up I'm putting a relay panel to sit on top the fuse box in the engine bay.

I'll break this out into what I do understand, and what I don't.
I understand the daisy-chain concept and had wondered if it would cause a problem linking several switches together with one that already does what you want it to. "Problem" as in draw too much and blow fuses. I also understand that the easiest way to wire D2 auxiliary lights is to get a switch that locks-down and stays on until you press it again (as in a cruise control switch).
What I don't understand is why two more fog light switches, exactly like the one I'm keeping, that turn on when you press them and stay on until you press them again, won't work if daisy-chain wired into the existing "factory" fog light harness with only the outbound load to the different relays/light assemblies changing. Do they have some funky form of relay?
And ... pardon my ignorace ... but I don't know what swifcb means (and apparently neither does Google).
