AUX Switches easy to use / hook-up!

[WKTJR1]

I'm a bit confused on the wiring setup. For my Limited, if I purchase the pigtails and switches is the wiring installed to plug into or do you need the OR or sport?

I'm showing the list price is $116, ~$83 from a discount dealer. Also, I seem to recall there are 4 part numbers.

Aux 1: 84484-35010
Aux 2: 84484-35020
Aux 3: 84484-35030
Aux 4: 84484-AK040 (84484-35040)

I was at Overland Expo this last weekend in CA. Toyota had a Trailhunter on display. It had the Aux 4 switch installed. Make me wonder how the truck is wired, and if they have different pigtails to wire them up.

Greetings I just joined the forum last night, as I found out from one of my wiring harness dealers SPV about the forum; but to the question of the auxiliary switches: on my 2024 trail hunter, it only has 3 AUX Switches. See photo. The 2025 Trailhunter has four switches. The part number for Aux4 above is correct (Aux 4: 84484-AK040) as I called my local Toyota dealer this morning, and he said it is on back order and more than two weeks out for $129 including tax. I told him I don’t care how long it takes. I need a fourth switch as the Trail hunters are all wired the same way they just didn’t include the 4th switch on the 2024 model. There are four “ports“ on the vehicle, two under the hood, one in the driver, left foot side panel, and one on the frame in the rear. The plugs are all the same using Toyota supplied pigtails on higher level, trim packages. I am using plug and play adapters that I purchased from Specialty Performance manufacturing in Indianapolis.(SPV). Ask for John. And this is not a commercial for them. I just happened to buy some rigid ditch lights last night as I am staying with the rigid brand since the trail hunter has rigid fog lights, and grill light bar.

Which company had a wiring harness on their lights that was plug and play with the pre-wired Tacoma pigtails? Cali Raised LED says they can't make theirs plug and play and still requires some splicing, which doesn't make much sense to me. Did Toyota use some super proprietary connector or what?

Plug and play harness can be purchased from Specialty Performance Parts (SPV). They can give you connectors wiring harness and other stuff. Ask for John. I am not a paid endorser. I have bought 3 in the last two months

Not to burst your bubble but I think the 24-25 harnesses are indeed different. Adding an Aux 4 switch will require more wiring than just plugging it in. The 24s only have 3 relays and 3 fuses relating to the aux switches.

I will find that out on Friday. My local dealer has 2(!) TH's on their lot. Will open one up and look.

Interesting. I just took delivery of my '25 TRDOR today. I know I only have Aux 1-3. I'll look to see if there is a powered Aux4 relay slot, and if the Aux4 fuse slot is powered.

So I went to my dealer today and looked under the hood of the 2025 TH relay/fuse box on driver side and took a photo. 1st photo just below is the 2025, the bottom one is mine 2024. It looks the same as my 2024 TH relay/fuse box

There’s another fuse box on the passenger side engine bay, maybe it’s over there

We looked and there was AUX5, then AUX 4 H and L. I did not have that. Need to get more info. I installed my ditch lights and plugged in the DT connector from SPV into AUX3 which is the "C" plug in the engine compartment, and currently waiting on UPS to deliver the harness this afternoon. When I get it I will post

My 24 sport came with 3 pigtails in the glove box.
One hooks to plug near filler neck of windshield washer tank and has 4 bare wires on the other end to hook to 3 things you want to power (from 3 aux switches)
Black AUX 1 15Amp fuse
Green AUX 2 10amp fuse
White AUX 3 5 amp fuse
White w Black stripe - Ground
The second pigtail is nearly identical to the first but only has 3 bare wires (ground and two hot from switches, then on the black wire (aux 1 )it has a plug that plugs in to the harness at the bottom of the washer tank neck and sends power to the back somewhere near the bumper.
The third pigtail (one black wire and ground ) then plugs into the harness in the back frame of the truck to power something in the rear.

I do have 2025 TH and they have 4 aux switches and want to know what amps on each of them. Thanks!

Should be in your manual

That's good info and all, but for a baja S8 40" light bar it pulls 16amps much less onx6+ pulling over 26 amps. I'm guessing for things like this you would have to run your own wiring. Please correct me if I'm wrong. I'm new to this light bar and preinstalled plug stuff.

You can also use the trigger from the relay and it wire to the AUX switches, instead of installing a separate switch.
That way everything stays in the engine bay.
