General Wiring Instructions

Model # SP-7550

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 re wall and fender well. Do not connect power leads to battery yet.

Drill a 3/4” hole in the re 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 re 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 conrmed turn power OFF. The electrical portion

of the installation is complete.
