WIRING AND HARNESS INSTRUCTIONS
4. Install the control side of the bracket to the
vehicle side using 1/4" x 1/2" Phillips head
machine screws, 1/4" nylon shoulder washers,
1/4" lock washers, and 1/4" hex nuts.
5. Plug the vehicle control harness into the cab control.
Harness Plug Cover
Install the supplied harness plug cover by slipping the
loop end of the cover over the harness plug.
CENTER HIGH-MOUNTED STOPLIGHT
(CHMSL)
An LED center high‑mounted stoplight is standard
equipment on all stainless steel hopper spreaders.
The orange wire from the spreader vehicle harness
is for the CHMSL. Splice the orange wire into an
existing CHMSL circuit wire tap. Location of the tap
varies according to specific vehicle model, and may be
located either in the cab or in the rear of the vehicle.
Always use the tap provided by the OEM.
DO NOT splice the orange wire into the wire coming
off the stoplight switch by the brake pedal. Splicing at
the stoplight switch may affect transmission shifting,
cruise control, or other vehicle functions.
For vehicles with a tap along the frame rail or at
the rear cross member:
1.
Cut the tape holding the orange wire where it exits
the convoluted tubing.
2. Pull out the orange wire to the location where the
vehicle CHMSL tap is located. Cut a small V notch
in the tubing for the wire to exit. Pull the wire
through the V notch and tape the tubing on each
side of the exit point.
3. Trim any excess length from the orange wire and
splice the wire into the vehicle tap.
4.
Coil and cable-tie the brown wire away from any
hot, sharp, or moving parts.
