    2016 Limited. I had read about this a while back and did it to my Tacoma and last Tundra. I couldn't find any wiring diagrams online so I had to test the wires.

    On my Tundra mirror harness the blue wire is +12v with ignition. White is +12v constant. White with black stripe is ground. I cut the white wire and insulated the end. Connected the mirror side of the white wire to the blue one.

    Done deal, buttons on mirror only work when ignition is on. Didn't want some asshat to smash in a window and then open my garage!

    Nice fix. I was surprised when I noticed that on my truck.

    Thanks for the inspiration! On my 2019 it was the Red wire that's +12v with ignition but all the same otherwise. Took about 30 minutes and that was being extra careful not to cut or burn anything with the soldering gun. Looks like factory work, and the mirror retains the code. I read somewhere that the mirror will remember codes for up to 4 months. Thanks for giving m the confidence to mess with a new truck!

    I like it. I’ve had the same concern, just haven’t done anything about it yet. It’s good to know that the mirror does not need battery power to maintain the programmed memory.

    Glad it worked out! I felt it to be a "must do" mod as my truck has to spend the night outside. Don't want to wake up to my tools gone and my deepfreezer cleaned out!

    One would think the power to the mirror would be cut if the alarm was triggered....no?

    Not sure how to test that... but in the event I forgot to lock my truck the homelink would still work, without the rewire.

    Now that's a Hell of a good idea! Does anyone think that Toyota engineers would have such a good idea?

    Noob here. I noticed that my homelink garage door opener works when the car is locked and nothing in the ignition...as I read the comments I’m wondering where do I do these modifications, Behind the radio or is the harness connections under the hood? Thanks for the information in advance! I drive a 2014 tundra crewmax 4x2.

    You might be able find it under the dash whilst lying in some horrific contorted position and chance splicing together your A/C and ABS.... Or you could just do it in a sitting position in the headliner with only one wire harness available to work on.

    I do suggest putting a meter on the wires to confirm colors. Small safety pin goes into connector and then it's easy to take readings.
