Important Note: IMPROPER WIRING IS THE #1 CAUSE OF PROBLEMS IN THE OPERATION OF A VEHICLE LIFT.
FOLLOW THE WIRING INSTRUCTIONS CAREFULLY
Located in the hardware package is the vehicle wiring harness. The harness is manufactured to, and complies with the
SAE J1128 requirements. The wire harness is approximately 23 ft. long and will accommodate most vehicles.
Begin routing the wiring harness at the vehicle battery.
Attach the black wire to the negative terminal on the battery.
Do not attach the red wire yet.
Important Reminder: Never attempt to attach the wire harness
to a secondary power source, The lift requires direct connection
to the battery.
Caution:
When the installation requires the wiring harness be run on the underside of a vehicle,
route the harness away from the exhaust system, brake lines, fuel lines, gas tank, p
inch points, and sharp edges.
Locate the wiring harness where it can not be snagged by road debris.
Manufactures Recommendation: Schedule a routine maintenance visit with the end user. Harmar recommends
the lift be greased in the applicable areas, and the wire harness connections be checked for corrosion,
and/or decay, as such conditions are normal due to environmental changes.
Unwind the harness and lay it flat. One end of the
harness has a black plug . This is the lift end of the
harness and goes to the back of the vehicle.
Run the wiring harness under or when possible through
the vehicle, back to the trailer hitch. Always locate the wiring
harness where it can not be snagged by road debris and
away from the vehicles gas tank.
If the harness is too long for the vehicle, coil the
excess wire and secure it to the vehicle frame with
the supplied tie wraps.
Do not cut or shorten the
harness.
Secure the plug about even with the end of
the hitch receiver tube.
Attach the red wire to the positive terminal on the battery.
