Step 1: Take harness assembly and route from the rear of the vehicle to the front. Route harness along frame and attach to
frame hole and frame supports. It is not recommended to attach to fuel or brake lines for obvious reasons. Do not route close
to exhaust system or engine, even though Snowex uses high temperature wiring. It still could melt under extreme heat and short the
spreader electrical system, as well as the vehicle electrical system.
Step 2: Mount rear plug on bumper using supplied bolts, locate towards the center of the bumper to reduce the amount of
debris the tires will throw to the rear. Important: Apply a small amount of dielectric grease to the plug.
Also try to mount so
plug faces upward to help keep plugs tightly sealed.
Step 3: Secure harness from the rear to the front using heavy duty ty-wraps or frame clips along the frame and lighter duty
ty-wraps everywhere else.
Step 4: Layout harness portion that connects to the battery along the fire wall and fender well. Do not connect power leads to
battery yet. Drill a 3/4" hole in the fire wall, or use existing access hole, for the control portion of the harness and route
connector and harness through hole. Be sure to check the area on the other side of the fire wall to make sure you are not
drilling into the vehicle harness or a control module. Generally you can drill on either side of the steering wheel for a good
location.
Step 4A: The power harness from control box to battery will need to be routed from the inside of the cab to the battery – this
results from the large high amperage connector. Route leads with lugs to battery — do not connect power at this time.
Step 5: Connect harness to the back of the controller and mount to a suitable location. NOTE: You may want to contact
customer before mounting controller as some prefer not to have holes drilled into the dashboard. Ty-wrap loose controller
harness and move to the engine compartment. Do not mount close to any heater vents.
Step 6: Connect power leads to the battery: Red + Positive, Black – Negative, always connect to the primary battery if using a dual
battery system. Secure loose loom to any other large or medium vehicle harness with medium duty ty-wraps; this will secure
wiring harness.
Step 7:
Push the ON/OFF button on the controller to check for power ; when that has been confirmed, turn power OFF. The electrical
portion of the installation is complete.
