So i have a 2016 base model explorer V6 4wd... i put a hitch on to tow a small trailer and a mobility scooter... install went fine til i got to the harness.. i got the t-one connector assembly ..part #118540 .. so there was supposed to be a plug to undo and then connect the harness to the 2 connectors... well on my explorer there was nothing plugged into the vehicles connector so i plugged the wiring harness in and taped off the open plug since there was nothing to plug into it.. checked the harness and it only works woth the left turn signal.. dont work with brakes or running lights turned on... i dunno what to do here... please help ..
