I'm wondering how you tap into them? Its there a power bar or something that you wire into? I should have my TRD Pro in 2 weeks and will find out then, but have been wondering, none the less.

There are actually wired AUX switches on some models. My Pro has 4 powered switches labeled Aux 1-4.
How do you tap into them, like is there something by the fuse box?There are actually wired switches on some models. My Pro has 4 powered switches labeled Aux 1-4.

Looking at mine, and at the manual, it's actually a different system than in the Tacoma. There are four different places to plug into, including one under the dash. I also did not find any pigtails included in the glovebox or anywhere else in the car.
The 4Runner hybrid has 2 plugs in the engine compartment and 1 under the dash. There is one more but I'm not sure where it is yet. You half to purchase the pigtails separately from Toyota.

I don't have the factory pre-wired AUX Switches on my TRD Off-Road Premium Hybrid, but I do plan to install some OEM switches like the ones from CaliRaisedLED to control the following equipment:
Switch 1: 40" RIGID SR-Series Midnight Optics light bar that will be mounted behind the half-height wind fairing on a Sherpa Capitol platform roof rack.
Switch 2: Clear and amber fog lights that will go into a C4 Fabrication Lo-Pro Bumper (like this one for the 4th Gen Tacoma) once they become available. They will likely be Baja Designs S2 Pros.
Switch 3: Scene lighting primarily for use in camp. These will be the Baja Designs LED Dome Light with Switch, which will be mounted in the side rails of my Sherpa Capitol platform rack like this. Because they each have individual switches, the lights can be independently turned on/off at the fixture, too.
Switch 4: The "Flux Capacitor" switch will turn on some clear high-vis LIN6 LED Strobes from Wicked Warnings surface mounted in the front grille. I'll have them tinted so the aren't noticeable unless they're on. I use these mainly for safety when I'm on job sites with my work.

I also plan to install a lightbar on AUX 1 switch. Just waiting for my 4Runner to arrive!
Looks awesome man. I am wanting to use "Flux Capacitor" for one of these rock light sets... But my brain can't only have one of the switches taken up!I don't have the factory pre-wired AUX Switches on my TRD Off-Road Premium Hybrid, but I do plan to install some OEM switches like the ones from CaliRaisedLED to control the following equipment:

Going to look into those side dome lights you plan to install on Switch 3.C-Series RGB Multi-Color Multi-Use LED 6-Light System - 5W Flood Beam

Yea I had posted up the DIY but asked for it to be deleted because the 4Runner's AUX wiring hook up is a bit different than the Tacoma. There's more than one pigtail harness cable and they plug into different locations in the engine compartment.
Hope someone will step up here and post up DIY instructions for hooking up AUX wiring.
How to use the Aux switches can be found starting on page 481 of the owners manual.

1. Power State Requirement
The vehicle power switch must be in the ON position for the auxiliary switches to work. These switches are designed for use only when the system is powered.
2. Using a Switch
• Pressing an AUX switch activates the corresponding power circuit.
• When a switch is ON, the indicator light on the switch illuminates.
3. Power Supply Behavior
• Power is drawn from a 12V DC circuit.
• Each switch is connected to its own fuse-protected circuit and corresponding pigtail wire connector.
• If the system detects low 12-volt battery voltage, it may automatically disable the aux circuits to protect the battery. It will re-enable once the voltage normalizes.
4. Wiring Accessories
• Remove the waterproof cap from the vehicle’s wire harness connector.
• Connect your accessory’s wiring harness pigtail (available from Toyota dealers).
• Do not modify the vehicle’s main wiring—doing so could cause malfunction or pose a safety risk.
