What mount did you go with? I’ve seen a few different version and they all mount in different spots

I went with these from NYTOP.

The high aux wiring works for the OT

Google Search. My dealer gave me this link which explains all of the connectors for the switches and locations.

It seems the 2025 4Runner Trailhunter and some PRO models also have a similar Aux setup as the 2025 OT, with the Aux 1 @40 A, Aux 2 @20 A, Aux 3 @15 A, Aux 4 @10 A. In reading some of the 4Runner G6 forums many, but not all, these models are coming with the pigtails in boxes, made in Mexico. I should have my 25 OT in about a month and will see if the Toyota pigtails work on the GX, if Lexus does not have them yet. The Toyota pigtails are different sizes for Aux 1 & 2 than 3 & 4 since they have more amps. The Toyota part numbers are:

PT974-89251
Hi AUX Wire Harness

PT974-89252
Low AUX Wire Harness

One is for Hi Aux 1-2, the other is Low Aux 3-4. Wonder when Lexus will have the pigtails ready, but just maybe the Toyota ones will work. The only downside would be that the wire colors are slightly different for the assigned Aux #'s.

Hi all, greetings from South Africa ... I just got my GX550OT here... Right-hand Drive... and am following this thread. I am a little confused however... there are 3 connection points; front left behind light, front right behind light and then in the cabin front left footwell (which will be the front passenger footwell for me) ...

Do all 3 connection points use a different pigtail or is it the Hi and Low current as per this reply here?

I am going to have a good look for the footwell(s) later to locate...

For my 2025 OT, I bought a Toyota 2025 4Runner Aux Hi pigtail to use for location C below from the US Owner's Manual, which is for Aux 1 and 2, and worked perfect for my 30-inch Light Bar. I don't know if non-US models differ. My understanding is the pigtail for the Aux 3 and 4 (Low Aux) is different and the Toyota part numbers are below for both. I don't know about the footwell connector B location. Good luck

still waiting on my 2025 OT, but would expect the 2025's would have the pigtail packed in a bag already, stashed in glove box or console, like in my Tundra and Taco?

'25 OT's did not come with the pigtails
