TIFFIN MOTORHOMES –PHAETON® Chapter 7 ELECTRICAL FEATURES
Seven-Pin Towing Connector
Your Phaeton is equipped with a
standard, 7-pin connector near the
towing hitch at the rear of the motor
home to supply the necessary circuitry
to control a towed vehicle. The wiring
of that connector is shown in the
accompanying diagram
(see Figure 7-16).
Make sure that any cable from the
vehicle to be towed is wired correctly
to mate properly with the 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 motor home.
When the towed vehicle is uncoupled from the motor home 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 motor home 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.
