Same. I think the larger of the two connectors is for aux 1 and the smaller is for aux 2 and the one in the cabin is for aux 3.

one of the pig tails I received has a larger connector than the other one. That's the other difference between the two part numbers...the connector size

Thanks. I’ll take a closer look. So I’m guessing Aux 2 and 3 are interchangeable for the last two switches.

so after a little more digging and reading the owners manual, I think I figured it out.

The larger connector pigtail, plugs into the engine bay near the front bumper, and handles aux 1 and 2 (4 wires, 1 power and 1 ground for each switch)

the smaller connector pigtail, plugs into either the engine bay (next to the larger) or in the cabin (under the steering wheel area), and handles aux 3 and 4. (2 power wires, 1 common ground, and a white wire that I have no idea does what yet)

to utilize all 4 switches, you only need two of the pig tails, the larger one, and the smaller one. It just depends on where the accessories that you are hooking up are. If they are on the outside of the vehicle, might be more practical to use the engine bay connectors vs the one in the cabin.

...more to come as I learn more.

totally makes sense. here's a question.. Let's just call the two Low Power Pigtails "2 and 3" for common language. Could you plug both pigtails 2 and 3 in and run Aux 3 off of Pigtail 2 and Aux 4 off of Pigtail 3? I don't really see why you couldn't as long as you tape off the unused wires?!?! maybe I'm missing something.. Here's what I'm currently planning..
Aux 1: ARB single compressor
Aux 2: Ditch Lights?
Aux 3: Extra fog lights when winch bumper is installed or Scene Lights
Aux 4: Midland MTX275 GMRS

Does anyone make a truly custom switch with your own artwork? I have two on my Gen 1 4Runner, one that says "Warp Drive" and the other says "Front Machine Gun" (they're really just clickers but still, seems a waste not to put something fun in the Aux locations.)

So for this part: "and a white wire that I have no idea does what yet" - yesterday I used this white wire to power my rear dash cam located in the trunk. I wired it to this white wire thinking it was one of the Aux circuits. It's not, and yet at the same time it is a source of switched 12v power. Meaning with all 4 Aux switches OFF, it still provides 12v when the vehicle is turned on. Bonus 12v power without using one of the Aux circuits I guess...

Edit - In the manual on P481 it does note that the white wire is Aux 5 that uses "power switch on*" instead of one of the Aux circuits. I consider this a huge win. Easy pre-wired switched 12v to power something I never want to switch on or off, without taking up one of the aux switches.

Did anyone get the pigtails with their car or did you have to purchase them?

I got mine from the dealership at purchase. That being said, I had to ask the sales rep to make sure the pigtails were included and they had to go grab them from a different truck.

The sales rep I purchased the car from told me I have to purchase those separately

Mine were included with my trailhunter along with the air hose for the compressor and a first aid kit
