Raise the snowplow and aim the snowplow
headlamps according to the Snowplow Headlamp
Beam Aiming Instructions included with the
headlamps, and any state or local regulations.
4. Check the aim of the vehicle headlamps with the
snowplow removed.
5. When the snowplow is removed from the vehicle,
install plug covers on the vehicle battery cable
and lighting harness. Insert the snowplow battery
cable and lighting harness into the cable boot on
the snowplow.
CAUTION
Plug covers shall be used whenever
snowplow is disconnected. Vehicle battery
cable is 12V unfused source.
VEHICLE LIGHTING CHECK
1. Verify the operation of all vehicle front lighting
prior to connecting the snowplow harness.
2. Check the operation of the snowplow lights with
snowplow mounted to vehicle and all harnesses
connected.
Turn signals and parking lamps
Parking lamps ON:
• Both vehicle and snowplow parking lamps
should be ON at the same time.
Driver-side turn signal ON:
• Both vehicle and snowplow driver‑side turn
signal lamps should flash at the same time.
Passenger-side turn signal ON:
• Both vehicle and snowplow passenger‑side

Headlamps
Move the vehicle headlamp switch to the

snowplow lighting harness plug should switch the
lights between vehicle and snowplow as follows:
Snowplow lighting harness DISCONNECTED:
• Vehicle headlamps should be ON.
• Snowplow headlamps should be OFF.
Snowplow lighting harness CONNECTED:

The dimmer switch should toggle headlamps
between high and low beams. The high beam
indicator on the dash should light when headlamps
are placed in high beam.
Daytime Running Lamps (DRLs)
An operational check of the vehicle and snowplow
DRLs will depend on the vehicle model, vehicle
DRL system, and type of Isolation Module
installed. Due to the variations in the OEM DRL
systems and the different Isolation Module
options available, checking the functionality of the
snowplow DRLs will depend on the type of module
installed on the vehicle.
OWNER'S MANUAL PACKET
If the completed snowplow will be delivered
immediately, the Owner's Manual should be reviewed
with and given to the purchaser according to the
snowplow checklist.
If the snowplow is completed prior to delivery to the
purchaser, attach the Owner's Manual packet to the
electrical cable of the cab control for safekeeping.
