I recently removed my hitch to do some work to it, reinstalled and when parking lights are on left blinker is hyper flash and all left lights flash, right blinker blinks at a faster rate but not the hyper flash and again all right lights flash. Checked grounds and all are good. Checked rear harness connectors and they seem to be tight and I couldn't push them together any further. Right side sometimes flashes normal and all turn signals flash normal when parking lights are not on. I have quality led tail lights that have been on the truck for 5 years without an issue. I am thinking it has to be in the rear tail light connector since that and the ground are the only things touched when hitch was removed. Any ideas?
