I just installed my fisher 3 port, 3plug isolation module on my 2017 Silverado. It was on my 2008 gmc sierra . I have led lights on the 2017 silverado, so I did change the lighting harness for the hid/ led harness kit. My problem is when I plug in the 11 pin plug, I have parking lights, but no headlights on the plow. Could it be because the plow lights are halogen?
