Attaching Plow to EZ Build Assembly
A. Liberally coat Pivot Pins (54) with Coolube Multi-Purpose Premium Grease
Part No. 15181.
B. Attach Pivot Bar (6) to Moldboard with Pivot Pins (54), 5/8”atwashers (52)
and insert Cotter Pins (53).
E. Attach Plow Markers (43) to moldboard using 5/16-18 x 1” Bolt (44), 5/16”
Flatwasher (46) and 5/16-18 Locknut (45)
F. Attach the Lift Chain to the Lift Arm (5) 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.
(5)
C. Attach Eye Bolts (51) to Moldboard and Trip Springs (42) to Pivot Bar (6),
making certain locknuts are positioned as shown below.
D. Make certain each Eye Bolt (51) is in a vertical position as shown below so
that the Eye Bolt (51) and Trip Spring (42) hinge properly when moldboard
trips.
Note: Proper tension is attained when Trip Spring (42) coils just begin to separate
and then tightening top locknut four additional turns. Tighten bottom Locknut
(20530) to secure Eyebolt in position. Install Eyebolt caps (07031) over exposed
threads.

Vehicle Side Wiring Diagram
G. Run Truck Side Control Harness (50) through a hole in grille and into the
engine compartment.
Secure Truck Side Control Harness (50) from any hot or
moving parts with tie wraps as needed.
H. Drill a 1-1/4” Diameter Hole through rewall to install split bushing (48)
and extend the harness into the cab of the vehicle.
I. Run trailer end of Truck Side Control Harness to the back of the vehicle
and plug into at 4 pin trailer connector on vehicle. Be sure to add
dielectric grease to the plug connection.
J. Route Power harness through grille of vehicle and connect red to (positive
post) and black wire to (negative post) of vehicle battery.
Top o the unit to the ll line on the reservoir with Meyer M-1 Hydraulic Fluid.
NOTE: Proper uid level is to the ll line on the reservoir for the E-73.
It must be checked with the lift cylinder fully retracted.
For snow plow light installation see separate instructions.
Connect both male ends from the snow plow light to the female ends on the
Plow Side Harness (25).
Check snow plow light blinkers to make sure the wires have not been reversed.
Note: All electrical connections should have both ends coated with a dielectric
grease, Meyer Part No. 15632, prior to nal installation. This will ensure a good
connection and help in preventing corrosion.
K. Refer to Operation and Maintenance Manual for complete controller
operation.

M. Assemble adjustable stacking stop bolts to lift frame (13) using 5/8-11 x
2-3/4” bolts (40), lockwashers (17) and jamnuts (34). See below.
Note: Adjustment must be made after moldboard assembly is installed.
Adjustment bolts (40) should make contact with the a-frame before any
part of the A-Frame/ Sector or moldboard come in contact with the lift
arm and, or hydraulic unit while raising the snowplow or stacking snow.
Moldboard should be checked in all positions.
1) Route into vehicle’s cab and plug into controller.
2) Route to the front of the vehicle and plug into the plow
side harness.
3) Route to rear of vehicle and plug into vehicle’s trailer
harness using the trailer adapter harness (54).
4) BLUE will connect to the vehicle’s keyed accessory
circuit.
5) White wire will connect to 2015 & Later GM vehicles with
alternator relay. See Meyer Products Service Bulletin SB252.
The following two steps are optional and may be enforced
by local law which requires your vehicle lights to be o
while your plow lights are on and vice versa.
6) Connect the RED to the HIGH beam function.
7) Connect the WHITE to the LOW beam function.
