On your 2014 Harley Tri Glide, there is an open circuit on that brown pin for your running lights. I recommend tracing that wire with a circuit tester like # PTW2993 to locate the short. It sounds like it was spliced in on the wrong side of your ignition and is drawing power from your battery all the time. If you have traced it all the way back to its origin, I recommend disconnecting it and finding another place to splice into the running lights like at your tail light making sure to splice into the running light and not the stop light since this is a two wire system for your dual filament bulb.

That certainly sounds odd. Here is what I would try: First, unplug the brake controller for 5 minutes and plug it back in. This will perform a hard reset on the controller which is sometimes necessary after a new installation. If that doesn't…

On both a 7-Way and 4-Way trailer connector the brake lights and turn signals are on the same circuit so it is strange that the brake lights aren't working. But, brake lights draw more constant power than the running lights or the turn signals so…
