I have the vehicle listed above and it has the OEM plug harness for trailer lights. I plugged up my trailer I have no lights of any kind for the trailer. all fuses look good. checked all of them and they are in good shape. do I have to have another harness just to be able to pull a trailer and make lights work? my trailer has no electric brake it's just a small utility trailer.
