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.

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, pinch 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.
