Allegro Bay Owner's Manual - Tiffin Motorhomes

ELECTRICAL FEATURESWarningNever replace a fuse with a fuse rated larger than that which originally came from thefactory. To do otherwise will cause serious damage, overheating of the wiring, andpossible ignition of nearby materials resulting in a fire.Seven-Pin Towing ConnectorYour Allegro Bay is equipped with a standard, 7-pin connector (Figure 7-14) near the towing hitch at the rear ofthe motor home to supplythe necessary circuitry tocontrol a towed vehicle.The wiring of thatconnector is shown in theaccompanying diagram.Make sure that any cablefrom the vehicle to betowed is wired correctly tomate properly with theconnections shown in theconnector. If in doubtabout proper wiring, have aqualified service technicianprepare and install thenecessary cable to mate withFigure 7-14. Seven-Pin Towing Connectorthe 7-pin connector on the motor home to assure proper operation subsequently when any vehicle is actuallytowed by the motor home.When the towed vehicle is uncoupled from the motor home and the cable is disconnected from the 7-pinconnector, be sure to close the spring-hinged cover plate on the connector to protect the contact pins from dirtor debris. In a similar manner, protect the cable end from similar damage, weather, or debris—one suchmethod 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 securedcable 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 againconnected to the 7-pin connector, make sure the resultant connection is tight and solid so that the connectionwon’t jar loose during use. Several supplemental methods to secure that connection have been used; some ofwhich include securing the connection with a strong rubber band or with Velcro-type fasteners to provide asupplemental mechanical backup to the actual electromechanical connection.7-10
