RE: trailer to truck electrical

well ,, don;t know why u have a nine pin connector on the trailer ,, but if it were me i would change out the connector on the trailer to what u have now ,, and as for the wiring ,, blue = trailer brakes ,, brown = running lights ,, yellow = left turn and brake light (if it applies to u'r tow vehicle) ,, green = right turn and brake ( same is applied as the above) ,, white = ground ,, and red is usally in most cases power form the tow vehicle to the trailer for charging the batt ,, but i have seen it used for the back up lights on some trailers also ,, some of the other pins left over are not even used ,, i may be worng on some of it ,, but hope this helps ,, and u come back and tell us what u find :approve: :approve: :approve:
