3) Route the 4 pin connector to rear of vehicle and plug into vehicle’s trailer harness using the trailer adapter harness.
Use cable ties to ensure the harness is secured to the vehicle’s frame.
4) The BLUE wire will connect to the vehicle’s keyed accessory circuit. This is to ensure the plow turns on and o with the vehicle’s igni-
tion.

Plow Assembly & Adjustments
Nite Saber LED LightsNite Saber LED Lights
See seperate Nite Saber LED instructions for further information.
Mount the lights as shown below.
Connect both male ends from the snow plow light to the female ends on the
Plow Side Harness. Ensure all wiring harnesses are secured against the lift
frame.
Check snow plow lights and blinkers to ensure proper operation. If operating
in reverse (i.e. driver side blinking instead of passenger side), reverse the har-
ness connections.
Note: All electrical connections should have both ends coated with a dielectric
grease (Meyer Part # 15632) prior to nal installation. This will ensure a good
connection and help in preventing corrosion.

Adjustable ClevisAdjustable Clevis
The 14700 adjustable clevisThe 14700 adjustable clevis is now standard with all Standard Operating Sys-
tem black iron packages. The 14700 Adjustable Clevis cannot be used with any
EZ+ Operating System plow model.
The 14700 Clevis oers 3 levels of adjustability for a height dierence of +/- 1.5
inches. To use the adjustability feature, mounting the clevis using two sets of
applicable holes. Use one of the bottom 3 holes to secure to the clevis to the
mount.
Level 1 = Rows 1 and 3
Level 2 = Rows 2 and 4
Level 3 = Rows 3 and 5
The clevis requires a height of 11.25”o the ground in order for the plow to sit
level.
Pivot BarPivot Bar
The Pivot Bar will need to be bolted to the A-Frame and Angling Cylinders. Cut
any ties that are securing the cylinders to the crate prior to removing black
iron from the crate. The Angling Cylinders will already be connected to the Lift
Frame. Hardware to attach the Pivot Bar to the Angling Cylinders and A-Frame
can be found in the Accessory Box.

Plow Assembly & Adjustments
Lift ChainsLift Chains
Attach the Lift Chain to the Lift Arm through the two hooks on the lift
arm. Adjust the lift chain at the lift arm so that there are 2-3 links of slack.
This ensures that the plow blade will lift fully and be able to follow the ground
contour while plowing.
Trip Spring AdjustmentTrip Spring Adjustment
Attach Eye Bolts to Moldboard and Trip Springs to Pivot Bar, making certain
locknuts are positioned as shown below.
Make certain each Eye Bolt is in a vertical position as shown below so that the
Eye Bolt and Trip Spring hinge properly when the Moldboard trips.
Note: Proper tension is attained when the Trip Spring coils just begin to
seperate and then tightening top locknut four additional turns. Tighten
bottom locknut to secure Eye Boilt in positiion.
Install Eye Bolt Caps over exposed threads.
Plow MarkersPlow Markers
Attach Plow Markers to moldboard using 5/16-18 x 1”Bolt, 5/16” Flatwasher,
and 5/16-18 Locknut.
Drop Speed AdjustmentDrop Speed Adjustment
E73 Drop Speed Adjustment: Loosen jam nut and turn knob clockwise to slow
the drop of the plow and counter clockwise to speed the drop of the plow.
Tighten jam nut.
