In the process of installing the Show Chrome/Big Bike Parts trailer wiring harness. The harness is a five wire setup and my trailer is four. I could go buy a converter but I am wondering if I can accomplish the same thing with two diodes. The trailer harness is left turn/right turn/ running/ ground. The Bike harness has a separate line for the brake lights. I figure I can "Y" the brake light line to the turn signals lines and just use diodes to prevent voltage from going to the opposite turn signal when one is being used. Just wanted to toss this out to those with more electronics knowledge to check my logic and see if the converter is providing something else that I am missing.
