Take a look in the Lighting forum, there are several good threads there with details on wiring using the upfitter switches. I don't have my truck yet so I can't help more directly with pics.

Not going to lie for a nearly 70k truck I think these up fitter switches could be better handled. Why not just have a block that you can wire directly into under the hood, clearly labeled and easy to get to with terminal for the hot wire and for the ground...

Just seems like a cool feature designed by marketing department and then butchered by the engineering folks.

+1; the lighting forum. The Raptor manual supplement also lists getting access.

There is a rumor that there are 12 wires, 6 powered, 6 pass through. It’s possible that they may be either embedded in the harness or hidden.

I found the 6 powered wires but if the other 6 wires do exist, they’re buried in my harness somewhere.

I was able to find both wiring harnesses under the hood. They are very close to each other. As you face the truck, the bundled wires on the left are powered (at least how they tucked them into my truck).

They are there, just hiding in plain sight. Wait until you look for the ones behind the passenger kick-panel! Get a flashlight and a mirror to see those darn things!

Or... I can have the Ford tech dig them out at my service [perhaps sweetening the deal with beer].

Spot on comment. I could not find them originally because I was looking for a terminal block. It never even crossed my mind that a manufacturer would just have wires dangling like that. This one goes under the category of "what were they thinking". Along side of no front parking sensors.
