Section 3: Wiring the Vehicle
Located in the hardware package is a vehicle wiring harness manufactured to comply with SAE J1128
requirements. The harness is approximately 20 ft. long and will accommodate most vehicles.
Unwind the harness and lay it flat. One end will have a black plug
designed for the mobility lift; it should be placed at the back of the
vehicle.
DO NOT ATTACH RED WIRE
Begin routing the wiring harness at vehicle battery. Attach the
black wire to the negative terminal.
• Run the wiring harness under or when possible,
through the vehicle, back to the trailer hitch.
• Always locate the wiring harness where it cannot be
snagged by road debris. Keep it away from the gas
tank, exhaust system, brake lines, fuel lines, pinch
points, sharp edges, and moving parts.
• If the harness is too long for the vehicle, coil the ex-
cess wire and secure it to the frame with tie wraps.
DO NOT CUT OR SHORTEN THE WIRING HARNESS
• Secure the wiring plug even with the end of the trailer hitch tube.
• Only after the wiring harness is routed through the vehicle and secured to the vehicle frame can
the red wire can be connected to the positive terminal on the battery.
Recommendation:
Regularly perform routine maintenance or schedule a maintenance visit with a
mechanic. The lift should always be greased in applicable areas and harness connections should be
free from corrosion and decay.
IMPORTANT NOTE: IMPROPER WIRING IS THE #1 CAUSE OF PROBLEMS IN THE OPER-
ATION OF A VEHICLE LIFT. BE SURE TO FOLLOW THE VEHICLE WIRING INSTRUCTIONS
CAREFULLY.
