I have a very weird situation with my running lights. I am installing a led undertail kit and just found out that my rear running lights have never worked. The fuse that goes to them is blown. when i replace that fuse my brakes, and turn signals dont work and neither do my running lights. as soon as i pull the fuse my brakes and signals work again..... what is going on?!?! The fuse says ind., meter tail illum. Another thing is there is a third plug where the brake lights plug in, there is nothing plugged into it. If anyone can help I would really appriciate it.
