2015 Side mirror turn signals

And...done! Heated, signal mirrors installed in my 3rd Tacoma.

I never get much faster though. The first one took me 9 hours, the next two took me 8.

NOTE: This time I did not hook into the sport mirror signals. It was way easier to tap into the (+) positive wires just below the mirror connector inside the door panel. I also grounded to a bolt in the door panel. For reference, on my 2014, the left side positive wire is pink, and the right side positive is blue with white tracer. Be sure to test before connecting though, just to be safe.

 

I just put some LED turn signals on my toolbox. Bam, cars in blindspot can see it

 

great idea! well done.

 

Damn! you beat me. You should have taken the bet, 'cause I had as much trouble as I usually have when i get into something I've never done before. Passenger side done the other day, driver side blew a fuse, didn't know where or what value it was, bought a Haynes manual to get the diagram, back to Autozone to get a 15A fuse, then discovered that the diagram was on the lid of the fuse box, along with spare fuses and a removal tool. Oh, well, I wanted the Haynes anyway.

OK, couple more hints:
Do the splice on the mirror harness inside the door. Screwed up the passenger door, spliced onto the door harness. Not a biggie, but don't tie the two harnesses together permanently.

Mark the door clip locations with tape so you know where to press when reinstalling. It's good to hear all those clicks. 2 hinge side, 3 latch side, 4 bottom. Careful, they can fall out easily.
The triangle trim piece at the top has 3 rinky dink clips that you'll invent several new words for. On removal, they'll stay in the door, so remove them and install on the trim piece first. The other way around pushes them inside the door, then you have to dismantle the door and start over. Ask me how I know.

 

Finally got some pics in the daylight. The last one was right after I finished, and it was too dark to get good pics.

Heated mirror switch

 

Did you have to use the "h-mod" from muth even with the highlander switch?

 

No, but you do have to use a relay or you will burn the switch up on the first try.

Here is the diagram on how to wire it. Thanks to CtryBoyInMT

Go HERE for the full instructions, which you will have to take bits and pieces from with the Muth mirrors.
