After instal, when jacked still, testing, brake controller in truck stopped wheel from turning, but not foot pedal. No codes, 2016 sierra HD. when on the road, no diff. Chnged the 30 amp fuse. The dash says the gain is rising when pushing the pedal, but the wheels don't seem to be slowing ( I can usually feel when they are active) . When I hooked the wires up, i left about 4 inches of the old brake wire and hooked to that, should I have removed this section ? There was not a lot of wiggle room in the wheel well ! Thanks for any hep. M
