I recently upgraded my rear tail light and rear fender tip marker to smoke LED. Then I started to install LED turn signals. The instructions tell me to land one of the turn signal wires (red/yellow) under terminal two of the fender marker connector (45b) but there is already a wire there. I am pretty sure this is the brake light signal out to the fender marker. I temporarily jumpered the terminal two output to the turn signal wire too and after a few moments blew the brake signal fuse.
I'm guessing it's either brake signal to rear marker OR turn signal, but not both.
This is a 2011 FLHTK.
