    I know how you feel. Luckily, I can back in at an angle to get my truck on my half of the garage. The parking lot at work can be worse.20200407_150240.jpg 20200407_150431.jpg 20200407_150451.jpg 20200407_150531.jpg 20200407_150557.jpg

    Nice work @TSands83. Great explanation.
    I dug deep into this a year ago and was in communication working with kTJO. I looked at the diagrams and felt it was too good to be true since the switch was can bus. I mentioned to her that it didn’t seem like it would be easy and I was definitely surprised when she said she had come out with a switch.

    The final straw that made me give up on the project was when I realized 200 series land cruisers have the 10 pin switch and we are 8. I knew something odd was up. I believe 1794s and platinums are the only vehicles in Toyota’s lineup that use can bus for the mirrors

    Hmm, upon further inspection of this 28-pin Toyota switch from KTJO, I would be a bit hesitant to plug this directly in to the 10-pin connector and run mirror motor current directly through this switch. The circuits imbedded in the PCBs are very delicate and there's a QFP48 microprocessor as well as 2 SSOP36 SMD IC chips. Obviously there's more than meets the eye here. I really wish I had a pinout or diagram of this switch and the vehicle it was intended for. I think that the 28 to 10 pin harness that KTJO was haphazard at best. Definitely a lot different than circuitry in my old 93 Supra used to be. But hey, I'm no expert or engineer, but I did stay at a Holiday Inn Express.
    I am curious since others have mentioned KTJO, if this switch has ever worked for anyone? If so, for how long?20201116_214805.jpg

    Wouldn't it be easier to wire up a little LED light right above it? You know like the ones in the strips or the little pinhole type.

    Glad I have no need to deal with this as I am the only driver. The only time I have adjust the mirrors is after I clean the glass. I drove my neighbors Prius at night once and switch is back-lit. If a Prius is then why not trucks?

    Yeah, it would be easier. It's been done here:

    Not really my style. The point here is to get a factory switch illuminated the way it should've been in the first place. Toyota went through all of the effort to incorporate CAN bus but overlooked a basic feature offered on practically every vehicle out today. All of the other switches around it are illuminated why not this one? When I give up, then I'll consider the other lighting methods or just live with it like everyone else. One of the things I miss the most about my 2011 Ram 1500 Sport was that EVERY switch was illuminated...what I don't miss were the problems it had.

    I think the best solution(although not an easy one) is to separate the current switch and replace the pad with a translucent one and add tiny blue LEDs inside. There’s a couple posts on it over on tundra talk. Looks factory and does the job, plus you don’t have to hack the can bus wiring.

    One con to this in addition to it not being completely OEM is that the mirror fold button won’t be lit.

    Well, good news for the folks with the 10 pin J130 connector (non-CAN bus)...it appears that the fully illuminated mirror switch that I got from KTJO 4X4 is indeed compatible for your application. I found these diagrams for the 12-18 Toyota Auris that uses the 28 pin switch.

    So, this is how the 10 to 28 pin adapter harness looks

    As suspected, the diagrams definitely confirm that the fully illuminated KTJO 4X4 switch is not compatible with the 8 pin CAN setup on the Platinum/1794 without some sort of interface. I still haven't heard back from KTJO 4X4 yet.
    I considered fabricating a flexible PCB for the LEDs and kitbashing the buttons. The larger button could be swapped and I could put 2 LEDS under that. However, the 2 smaller buttons are completely different in construction and there's no clearance under them to mount any LEDs. The mirror select switch contacts are positioned differently and the retract button mechanism is completely different. Even hacking off the front of the housings and swapping them wouldn't work. At best, I would end up with a lower half illuminated switch or a Franken-switch. Nope.
    To be continued...

    Wish there was a illuminated Non-power fold switch.
