Figure 9-8: Seven-Pin Towing Connector
The wiring of that connector is shown in the accompanying diagram (see Figure 9-8 ).
sure that any cable from the vehicle to be towed is wired correctly to mate properly with the
Make
connections shown in the connector. If in doubt about proper wiring, have a qualified service technician
prepare and install the necessary cable to mate with the 7-pin connector on the motor home to assure
proper operation subsequently when any vehicle is actually towed by the motorhome.
When the towed vehicle is uncoupled from the motorhome and the cable is disconnected from the 7-pin
connector, be sure to close the spring-hinged cover plate on the connector to protect the contact pins
from dirt or debris. In a similar manner, protect the cable end from similar damage, weather, or
debris—one such method could be to place the connector end in a heavy-gauge plastic bag (e.g.,
polypropylene, polyethylene, etc.) and secure the bag tightly around the cable with a stout elastic band
or tape and then mount the secured cable in a manner to keep it both from mechanical damage and
water intrusion
.
When the towed vehicle is again coupled to the motorhome via the towing hitch and the cable is again
connected to the 7-pin connector, make sure the resultant connection is tight and solid so that the
connection won't jar loose during use. Several supplemental methods to secure that connection have
been used; some of which include securing the connection with a strong rubber band or with Velcro-
type fasteners to provide a supplemental mechanical backup to the actual electromechanical
connection. Should a conversion adapter to convert the round, seven-pin connector to a flat, four-pin
connector be needed; such an adapter may be purchased from any RV after-market store.
