CENTER HIGH-MOUNTED STOPLIGHT

(CHMSL)

An LED center high‑mounted stoplight is standard

equipment on all HELIXX™ poly 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 into the vehicle tap.

Coil and cable‑tie the brown wire away from any hot,

sharp, or moving parts.
