I spent a fair amount of time trying to find if someone tread this path before me and found similar installs/info, but nothing that satisfied this use case. So if there's another post that has another method, lmk.

The goal here is to populate the 5 blank switch spaces in my non-hybrid ORP with caliraised OEM style switches, where everything is prewired and the accessory just needs to be wired up to an awaiting terminal block. I took inspiration from the overland equipped aux power kit. I thought it was a bit expensive so I looked for alternatives.

In this design, the main breaker is 100 amps supporting a 12 position 100A fuse block w/ negative bus (for potential expansion), 5 relays, a hot and ground terminal block. The wiring should support the switch backlights coming on with the headlights if I can indeed find a fuse to piggyback from for those switch leads. If not, it can go to the relay along with the green wire. It only requires 9 total wires run through the firewall.

To add an accessory, pick a switch and just run your positive to the terminal block and negative to either the ground block, or negative bus on the main fuse block. Add the proper fuse for the circuit and you're done.

Rather than OE's AL plate bolted to the fuse box, I'm going with a piece of ABS that will cover the fuse box and extend into the empty space next to it to accommodate the terminal blocks and relays. The whole shebang shown in the diagram (not including the switches) comes in a quite a bit less than what the OE package costs ($230) for just the plate, breaker and fuse box. The Blue Seas 12 circuit fuse block, identical to what they're selling is 30 bucks, a breaker is $10, and 20' of 4 awg is $20.

I’m also wanting to populate the existing blank switches instead of using an auxbeam pad. I keep hearing the existing aux wiring isn’t fully installed on our models?

there is no aux wiring in the ORP unless you have a Hybrid. super lame if you ask me. The hybrid people just have to plug in and its ready to go

I appreciate your efforts, I'm wanting to add ditch lights and possibly a light on roof rack

Really? You're saying that my ORP iForce Max already has AUX wiring to the blanks, even though I didn't buy the AUX switches option?

Correct.... it's ready to go
However, after reading the other threads on this topic, it appears the fuses and relays for the AUX circuits are not there and not wired to the fuse box on the ORP iForce Max without the AUX switches option. Is this correct?

The Hybrid should have the Aux switches and from what another use posted... they ran ditch lights to the connector in the engine bay and hit the switch inside the cabin and ta da let there be light sounded like a 10 min job. I have a non hybrid so I can not verify 100%

I have an ORP iForce Max and I just checked. The relays and fuses for the AUX circuits are empty and not wired at the fuse box.

I went through the fuse box with a multimeter, there are no circuits that are activated by the headlights on either driver or passenger side. I was able to find an unused (not fused) slot that did get power when the truck is on. ECU-IGP #3 on the drivers side. It takes a low profile mini style add-a-fuse.

So that will be the piggyback circuit for the switch backlights. Not ideal to be on at all times when the ignition is on, but better than splicing into the factory wiring, which is also one of the goals of the project.

Aux switches are an option on the hybrid ORP, and standard on the Pro and Trailhunter.

If you don't have the Aux switches, you do not have the supporting wiring/electrical system. Hell, the aux switches add a whole ass alternator to the thing, something none of the other hybrids have.
