TIFFIN MOTORHOMES –ALLEGRO RED® Chapter 7 ELECTRICAL FEATURESWarningNever replace a fuse with a fuse rated larger than that which originally cam 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 RED is equipped with a standard, 7-pin connector near the towing hitch at the rear of the motor home tosupply the necessary circuitry to control a towed vehicle. The wiring of that connector is shown in the accompanyingdiagram (see Figure 7-16).Make sure that any cable from the vehicle to be towed iswired correctly to mate properly with the connectionsshown in the connector. If in doubt about proper wiring,have a qualified service technician prepare and install thenecessary cable to mate with the 7-pin connector on themotor home to assure proper operation subsequentlywhen any vehicle is actually towed by the motor home.When the towed vehicle is uncoupled from the motorhome and the cable is disconnected from the 7-pinconnector, be sure to close the spring-hinged cover plateon the connector to protect the contact pins from dirt ordebris. In a similar manner, protect the cable end fromFigure 7-16. Seven-Pin Towing Connectorsimilar damage, weather, or debris—one such methodcould be to place the connector end in a heavy-gauge plastic bag (e.g., polypropylene, polyethylene, etc.) and securethe bag tightly around the cable with a stout elastic band or tape and then mount the secured cable in a manner tokeep 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 tothe 7-pin connector, make sure the resultant connection is tight and solid so that the connection won’t jar loose duringuse. Several supplemental methods to secure that connection have been used; some of which include securing theconnection with a strong rubber band or with Velcro-type fasteners to provide a supplemental mechanical backup tothe 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.7-12
