I've been searching high and low for a step-by-step like this. I'm happy to say that I've put this mod in motion.
Parts ordered: Check. Losing my mind waiting for parts to arrive to begin this mod: Double Check.
It is to my understanding that this step-by-step is being done on mirror already equipped with turn signals?
My 08 TB didn't come stock with turn signal mirrors but I've already tested my DDM & FPDM to verify that the turn signal supply voltage does exist and i don't believe I should have any issues tapping these LED modules straight into those supply voltage wires?
