I know you text us but easy fix.. cut the harness. Meaning after the relay, where it goes to the switch. Cut that off. Whatever went to the switch for on/off... that'll go to your upfitter. THe upfitter will turn the relay on, which will turn the lights on.

2 harnesses can be twisted together and you can use 1 upfitter to control both relays. OR you can do it via 2 switches.

I don't have their relay harness in front of me (we do at the shop, but im home right now).

But their harness has (from what I remember) a switch that does 2 functions. 1 = high beam mode and 2= low beam mode.

I would not waste my time worrying bout low beam mode, unless you WANT low beam mode (that'll eat up another switch). So you're only going to use the high-beam one. I'd have to have the switch in front of me to tell you which one is which. So you'll need to just do some testing with a multi-meter (test for continuity on the switch to find the right wire).

Or you can follow the wires back to the 4-pin DT plug to figure out which wires for your high, which is for the low.

Basically you'll use your upfitter as the TRIGGER wire on the relay (which is what that rocker switch was doing).

If you're not that familiar with relays and what not it's going to be a bit difficult to explain this to you though, to be quite honest.

Running mixed set of Baja Designs LP6 and LP9’s on an N-Fab bumper from 4x4truckleds.

Quite a wiring exercise to connect new relays to AUXs. Install instructions in box didn’t help, had to email BD for detailed assistance that was still a bit complicated for me. ultimately cut and threw away most of the harness and excessive wire/switch/relay provided in harness.
It would have been nice if either Baja Designs or Ford included detailed wiring diagrams for installation to upfitter switching.
I made decals with glow in the dark decals for AUX switches

What is that 5 light array in your front corner bumper cut-out?
