7-Prong Connector
The trailer connects to the tow vehicle with a 7 prong connector.
The connector has a raised rib along one side to orient the connector
when mated. The cover or door on the tow vehicle side of the connector
has a locking detent that engages with the raised rib to lock the connector
when it is fully engaged.
Before mating, inspect both connectors for corrosion on the contacts. If
light corrosion is present, plug and unplug the connector several times.
Usually this is sufficient to self-clean the contacts. If the corrosion is
more severe, you can scrape it with a tool or clean with a small piece of
sandpaper. In the most severe cases, the connecter will need to be
replaced.
To minimize corrosion and dirt fouling, the connector should be stored
so it is not in contact with or near the ground.
