I have seen similar posts, but not exactly this. I will breakdown exactly what is going on.

My current setup: 1 - 40" Rigid Light Bar, mounted behind grill hooked to upfitter 1 (21.36a draw)
4 - Rigid D-Series Pod Lights, mounted in SVC Front Bumper hooked to upfitter 1 (2.14a draw per light = 8.56)
2 - BD S1 Sports, mounted as chase lights on rear SVC Bumper, hooked up to upfitter 3
2 - BD S2 Pros, in my third brake light, also hooked to upfitter 3

A couple of months ago, I lost all of my forward facing lights that have worked the past year and a half, and have just recently gotten around to fixing this.

Where I started, checked fuse #18, check the inline fuses, and the inline relay (it was wired very strange from previous owner, have gotten rid of this setup now). Everything tested good, and nothing appeared to be broke. Went on to individually test each separate light, and all work when hooked directly to power. After discovering all of the lights work and the grounds were good, I figured it must be the power coming from upfitter #1. I tested for power at my pass through wire, and nothing. So this is where I am kind of stumped, the relay in the fuse box is providing power to the switch, or so I assume because the light on the switch works. Unless there are two wires that come into the upfitter switches, one supplying the 30a power, and another providing power for the light on the switch. So this is kind of the end of my knowledge, and figured I would be better off reaching out to you guys.

What I am doing to fix the current wiring mess.

I am hooking a relay to upfitter #4's pass through wire in the engine bay, where #4's power will control the relay. I am then hooking up 8ga wire to the battery, where I have installed a 40a inline fuse, and have this providing power to the relay/forward facing lights. I then have my forward facing lights hooked up to the other corresponding pin, with more 8 ga wire, and the relay grounded to the battery.

All insight is appreciated, thank you!!!!
