I have Hazard lights and turn lights I don't have running lights or brake lights. This problem is in the tow vehicle. I installed a Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
Item # C56320 and the wife said all lights were working that day ( last week). I was using a magnetic light set up to transport home as the wiring pigtail had been cut off by some jackwagon. I put one of those little light test plugs into the Tow vehicle pig tail and it shows full amp or full light on the turn sig. but in the brake it is very faint, lit but faint.
If it were a fuse then it wouldn't even be faint would it? I checked the underhood fuses and didn't see a problem unless I missed something. How would I even know which fuse it is? I checked the one fuse next to the battery that comes with the wire harness and that was fine.
Any ideas?
Thank You
