2012 Tundra turn,brake and hazards

Hey there I am new here and I know this has been covered a few times however my situation seems to be difficult! I am trying to diagnose hyper flash on my 2012 tundra. I recently installed a flat bed,(still in progress). I needed more room for sheet goods for work, and for a flat bed camper build. Anyway I tried modifying the two sold dongles by removing them in the flasher module. Unfortunately with no success with fixing hyper flash. I am going to led in the rear.

 

I would rather remove this module altogether and build a custom module to support my needs . But need the correct wiring and diagrams with details of the correct wiring color.

 

I was able to isolate the blinkers and hazards from the rest of the truck. Boy what a pain. The green wire coming into the flashing relay box under the dashboard can be tapped into for the right turn signal and the beige Color left signal wire on the left of the plug .

 

Why didn't you just install load resistors inline with the led lights and call it good? Maybe I'm missing something

 

Believe me I tried my truck didn’t like them for whatever reason.
