I currently own a 2001 GMC Sierra 1500 with a ultramount to unimount set up. It has a three plug set up. Up until recently everything worked fine. I just switched out the glass bulbs in the lights for led bulbs. And now as soon as I connect the light harness my high beam indicator on the truck cluster comes on. But the low beams are on ,and I loose my high beam function. Any ideas what it can be?
