Added MTS/Crawl Control switch to Platinum CrewMax

Thanks bud!

 

Just tried installing on my 22 sr5 4x4 with convenience package and it didn’t work unfortunately. Going to be selling mine if anyone in the Phoenix AZ area is looking for one.

 

OK, I just tried to put the switch in mine and I can barely get the front of the current switch up enough to even shine a light in there. Definitely can't pull the back of the switch up any further. There was little to no slack in the wiring below and I'm cautious about pulling too hard and causing an unnecessary issue.
For those that were successful, how were you able to get enough room to pull out the plug? I've got a 2025 Limited.

 

Once you got the switch unhooked / released from the snap fits, tilt it back towards the center console since the hook on the plug faces the front of the truck. Then you can bareeely fit fingers or a screwdriver in there to unhook the plug. My wiring harness was also super tight. Plugging in the new switch is even more fun. I still haven’t replaced my MTS switch with the old one bc I’m not motivated to do that again. Good luck!

 

Basically this. I also have a 2025 limited and the harness was super tight. I pretty much “fondled” it until I was successful, lol. I almost gave up and asked my wife to get her small hands in there to see if she could connect the harness.

 

Pop off the small side panels and you can stick your fingers to hold the harness up while you plug it in. This is what I did on my 24.

 

I'm bummed, I added the MTS/Crawl switch assembly but MTS doesn't work. I knew crawl wouldn't but hope that MTS would. I disconnected the battery, nothing!
24 Limited 4x4 crewmax. Non OR.
Would a zero point calibration help at all?

 

I have a 24 Limited as well & it works fine. Did you put it in 4wd & make sure it was locked in before you tried the switch? That's been one thing that a few overlooked.

 

I too have a 24 limited crewmax and it worked fine with MTS. You must make sure that 4H or 4L is engaged first.

 

THank you for replying, unfortunately I tried it all. Closed doors, drive D or R, 4i, 4h, moving, not moving... nothing! Oh well, the buttons look cool...

 

Do you have the hybrid? Anyone else non-hybrid limited 4x4 get this to work? I wonder if it is only hybrids because the whole Offroad and Trd pro line are hybrids. Would make sense for the limited hybrid 4x4s to be the foundation for the TRD lines.

 

People with non-hybrid have had it work. Even an SR5 without the PVM. It’s a mystery so far.

 

I wonder if the brake booster / ABS module is different on some. If not, I’d imagine it’s a software based thing, right?

 

I would say technology package with the full digital screen display for graphics. But I recall someone here had one with just the small screen and analog odometer. I could be wrong. It’s been a while since I have read through this whole thread and I don’t plan on doing it again for my own sanity.

 

Yes, I’m one of the SR5s without PVM that has it working. Actually just used the MTS mode this last weekend on a trail I was on. It worked great. I thought it may be wiring differences at first but that was debunked so don’t know what’s different.

 

This one was me. I have the SR5 with analog gauge and small radio screen.

 

This makes me feel better. Remembering that made brain hurty.

I’m glad we got around the Offroad upcharge. We should make custom badges “TRD OffRoad sans Crawl” for our trucks. Then we can silently nod with approval at one another as we pass by.

 

It’s a complete mystery, I have the hybrid with digital gauges, big screen…
Considering looking at the 4x4 control module!?

 

What packages do you have on your truck? EX: Limited Premium Package.

 

Sans locker. That’s where the upcharge comes from

 

Same thing happened to me. I decided to order the 4WD computer from a totaled Tundra as a last ditch effort. Going to try installing it this weekend.

 

Installed the MTS switch in my 25 Tundra Platinum and everything works, except the crawl. I was able to pop the left side of the console off and push the 4wd switch out and unplug it. Used a trim tool to pry up on the MTS switch via the 4wd switch opening, it popped right out. Had just enough slack in the cable to release the old one and plug in the replacement. Took all of 5 minutes.

 

This is the way. Thanks for the directions, spot on for my install.

The switch came a day late. I was on the beach fishing yesterday. I aired down so there with no issues without have sand mode

 

Did you get around installing the 4x4 module? Did it work?

 

Success!
Got the switch installed and functionality is as described by others, without the DAC crawl control. Engaged 4WD and could see all modes available. 2025 Limited with PVM, etc.
The secret was as @nkawal said, pop the side panel off, pop up the 4WD switch and then you can get to the MTS switch. I did also pop the harness clip out and separate the two wire looms zip-tied together, which made it really easy to change out. Longest part of the process was getting the clip out and cutting the zip tie.
Thanks all for the practical advice. Fun mod and nice to see a little more dash animation.

 

Hello all,

I just swapped it in my 2024 Tundra SR5 non digital screen and it worked. Gave modes in 4H and different ones in 4L too.

 

Do you have the PVM?

 

No I don’t

 

Nice, thanks, that’s the second sr5 without that it’s worked on. I might have to try it

 

I didn’t have high hopes but my dealership told me if it didn’t work I could return the switch and get a refund so thought why not. I have yet to actually test it out in the wild hopefully the coming weekend.
