Section 2  -  Wiring the Vehicle
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, 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.
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.
