I installed your harness on my 2011 jeep liberty and, the running and/or the blinkers dont work on the trailer. I have tried the trailer with my other vehicle and all lights work fine. I have checked the ground and it is good. Pls help!!! r, Chris Jones

So far you have eliminated the trailer and ground from what could possibly be wrong with your setup. The first thing I would do if you have not already is just remove t-connectors and then push them back together just to make sure they are making good contact. Hopefully it is just a situation where the terminals are just not making good contact.
The next thing I would check is for the correct voltage on the input side of the convertor box. I would recommend using a circuit tester like our part # 3808 for this. If you find that there is the correct voltage going into the box but none coming out of the box on the running lights or blinker then you know the box is at fault. If there is not voltage going into the box you will need to go up to the connectors and see if there something wrong in the t-connectors. Did your vehicle blinkers and tail lights function correctly with the trailer wiring installed?
