Factory Tow Wires (w/o tow pkg.)
2011 WK2 (w/o tow pkg.) however, under rear bumper found factory installed tow wires (7 pin pole). The running lights work fine on boat trailer and travel trailer. However, the STOP and SIGNAL not working on trailers. I put in 10a fuse into M4 fuse bay and still not working. Any other ideas w/o going to dealer?
