Adding Trail Turn Assist to a 2024 Lariat

I have a 2024 Lariat Ultimate 7.3. I’d like to try to add Trail Turn Assist like a Tremor, but first I need to find a Tremor transfer case control switch. I’ve looked and looked online but can’t figure out the part number. Some parts sites list 4 different switches even when I put in a VIN from a Tremor. Some list Level 1 and Level 2 option packages, but I have no idea what that means. Another member asked about adding this feature and posted a photo of the switch in his post which I’ve copied below. Can anyone tell me the part number of the switch in the photo?

Can't help with the part number, but out of curiousity why do you want to add trail turn assist? It is a VERY limited use option, as you can only really use it on the loosest/slickest surfaces. I haven't tried it in my Tremor (that's a lot of weight to be slinging around), but we used it once on our Bronco on a snow-covered gravel parking lot. It cut the turning radius in half, sure, but most places I would need to be able to turn like that, the ground may not be soft enough to avoid breaking things. Been several Bronco owners who used it who have broken things when the ground wasn't soft/loose enough.

I hear you on the limited use, I’ve had my truck for two years and haven’t wished I had trail turn assist until last weekend. My friend’s SxS broke down miles down a wash with loose sand and course gravel. Tried pulling him out with my SxS but it just kept digging in. Decided to use my truck with the tires aired down which did the job, but there were lots of twist and turns and intersecting paths with tight turns. I didn’t want to scratch my truck on all the bushes so after the 20th time backing up and making a 3-point turn I thought back to the videos I’d watched showing the Tremor trail turn assist when they first came out. Seems like it would have worked great in this situation so I started researching to see if it’s possible to add it. Turns out the first hurdle is simply trying to find the switch.

Thank you so much! I’ve been to the dealer and have emailed two different online parts places. One of them did suggest this may be the right part number but there were no photos of the switch, only a diagram. This really helps me out.
