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.)
