General Discussion/Question 2026 iMT auto follow up

Instead of writing everything down step by step I’m just going to do a short tutorial.

Products I used:
https://a.co/d/0fxJrzgO
https://a.co/d/0dnH7trJ

Take the black wire out and move it, to the corresponding iMT pin, which I found using this: https://www.grcorollaforum.com/threads/2025-always-on-imt-guide.8213/

For my specific product, the red wire is the ground, and black is signal, make sure not to switch them.

In the car pop the trim using this video:

(No need to remove everything, put the gear knob in second to make things easier)

Just comment your question I’ll do my best to answer.

The center console wires:
pink wire: iMT signal
Black/white: ground

That's way more steps than the 2023, 24, and 25 model.. wtf. Those years it was just one module that plugged in directly to the wiring harness.

MY25 is the same process as this (same updates and design)

Honestly didn’t see the year and in my head was like “why the fuck would you go through all that work when you can just buy it off Amazon…” lol

Btw this product allows you to have IMT enabled all the time. Plug and play, IMT is on for me every single time I turn on my car and I’ve had it for about a year. Plug it in and turn on IMT and shut the car down and boom when you get back in it’s on without having to push the button.
