Guys, I've integrated custom LED lights into my mirrors, similar to newer factory models but mine look way better BUT, one big problem im having is after running my wires for the blinker mirror's LED lights through to the floor board of the front doors, I've come to realize there's 80+wires in the loom running down the jam of your doors. Also, none of the wires match the color of the rear blinkers if you go to the rear of the car and check.. I've found them to be white/blk stripe, and green/yellow stripe.. Those do not exist in the loom pictured in my attachment of this post.. Please help guys.. car's torn apart and I'm anxious to see the puppies light up!! Looking for, in the section circled below, the two correct colored wires that run to the rear blinkers.. This is my last hope, not even Lexus of Ft Myers could help me out here.. Thanks so much! If possible, cuz I may not check this often and im looking for answer ASAP, text me the colors if you could 239-289-2942. Big help here!

 

I added LED signals in my mirrors on another car. I didn't want to cut into the harness on the floor to reduce the chance of damage in the future.

I tapped into the turn signal wires in the harness behind the rear wheel. It had a lot of room behind the rug, it was out of the elements and I was 100% sure that I had the correct wires. I ran the pair of wires up both sides to the doors along side the main harness.

edit: I just checked your PDF file and that shows where the wires are run. You need a schematic to show what the colors should be. I also noticed that the Lexus has the harness on the drivers side.

The GM car I worked on had wires on both sides. You might find it easier to tap into the headlight turn signals or the BCM or whatever Lexus calls it.. The colors should be the same.
