2004 Dodge Ram 3500 Pickup Owner's Manual - Page 273

STARTING AND OPERATING 273 2500/3500 Models • The Axles on 2500/3500 Models are trailer tow ready and DO NOT REQUIRE any special axle lubes or additives. Trailer Towing Recommendations • All trailer hitches should be professionally installed on your vehicle. • Safety chains must always be used between your vehicle and trailer. • Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury. An electrically-actuated electric trailer brake controller is recommended. • Trailer brakes are recommended for trailers over 1000 lbs (454 kg) and are required for trailers in excess of 2,000 lbs (907 kg) • Use an approved wiring harness connector on the trailer. Standard equipment on all RAM pickup models provides a 4-way trailer tow connector located under the bumper. This connector contains the following vehicle circuits: park/tail lamps, left stop/turn lamp, right stop/turn lamp, and ground. With the optional Trailer Tow Prep package a 7-way connector is provided with the following additional circuits: backup lamp, trailer battery and electric brake. NOTE: Connect trailer lighting and brakes using factory harnesses only. Do not cut or splice wiring to the brake circuits. 5
