I'm installing the JCR roof rack with light bar cutout.

I have a Rigid SR Pro 40" midnight light bar to go with it. https://www.rigidindustries.com/sr-srs-pro-40-mdnt-940214blk.html

The light bar draws 18.5 amps. I have a "generic" wiring harness with relay but I have no plans to drill up top in the window frame. I plan to use Ford's method of routing the wires found here: https://performanceparts.ford.com/download/instructionsheets/IS_M-15200K-BRL_BRRL_9-1-22.PDF

I mean there's no reason to use the extra harness at all, correct? I can just wire to Aux3 and should be golden.

That's at least my plan for now. I will likely add a bumper-mounted flood/driving combo at some point and have the upgraded Rigid Ford Performance driving lights in the inboard fog location.

-The OEM fogs are still wired to the light switch on the dash.
-The FP Rigid driving lights are wired to Aux 1 just as the originals were.
-The new roof-mounted light bar will be to Aux 3
-Not sure which switch I'll use for the bumper lights

I still have the OEM fog and new Rigid driving lights wired separately so I can run the fogs on the road day in and day out although I never really encounter any serious fog these days and I live in a major city. So eventually I may just wire both to the dash wire. Thoughts? Seems like all I need is the OEM fog connector/splitter to do that and not the Aux 1/Fog switch relocation harness.

Wiring wise, I currently have:
-Generic harness
-SPV 2-way Raptor OEM Fog Connector Splitter
-SPV Aux 1 & Fog Switch relocation
-A lot of extra 12Ga and 14Ga wire and a ton of D2 connectors left over from other projects when I was manufacturing trans cooler kits for dual clutch gearboxes.

I do plan on possibly adding a fridge to the rear for a road trip up North this fall. But there's a 12V back there so not sure if I'll need to run any lights to any of the other aux switches. I'll be adding a Starlink as well as a portable battery and solar panels. We may camp, we may glamp. Bringing a tent as a backup in case wildfires change our plans.

Can't really think of anything else I "need" at this point, maybe an air compressor although I won't be doing any serious rock crawling on this trip. I do plan on hitting up Engineering Pass in Colorado either on the way up or way back but not even sure I'd need to air down for that? There isn't much off roading where we're going, Glacier National and Yellowstone. Plus I don't want to get stranded or break down 1500 miles from home with the wife in the passenger's seat.

Thoughts and ideas appreciated!

I ended up spending the entire day installing the rack and light. The rack installation was extremely fidgety to say the least but I got 'er done round midnight, LOL. I still have to connect the passenger kick panel wires and the wires under the hood but that'll take me all of five minutes. I'll let you know if it burns to the ground.

Curious, how do people aim roof mounted spot light bars? Aim where high beam end? And yes, it does fit out the garage. I still have about 3" clearance.

I have a combination of flood & spot (KC Gravity Pro 6) roof mounted and aimed so they cast light about 2/3 of the length of my low beams. I recently did some night wheeling and this placement worked out great for me (not so much for the guy ahead of me tho).

Here’s a video taken from behind my rig and you can see the light pattern based on the on/off.
