INSTALLATION INSTRUCTIONS
3.7 Checking High-Intensity Discharge (HID) Auxiliary
Light Wiring
Some M155 E4 Self-Propelled Windrowers from model year 2015 were updated in the factory with the Auxiliary
Lighting Harness kit. However, It may have been installed incorrectly. Before installing the Auxiliary Lighting
Harness Repair Kit (MD #167693), check first if it’s already installed in the machine and if it was installed correctly.
To check, do the following:
1. Remove the left headliner switch panel to reveal the
auxiliary lights relay and socket.
2. Locate a red wire labeled AUXILIARY LTS (A) on
the relay.
NOTE:
There should be two wires labeled AUXILIARY
LTS—an orange wire and a red wire. The red
auxiliary wire is the updated wiring harness.
3. If there is no red wire labeled AUXILIARY LTS on the
relay, then install kit MD #167693 using instruction
MD #147762 included in the kit. There is no need to
install the kit if a red wire labeled AUXILIARY LTS is
already installed, just continue on to the next step.

4. Check the connection of the AUXILIARY LTS (red)
wire on the relay.
If the wire is connected to
port 30, then verify lights are functioning properly.
Refer to windrower operator’s manual or instruction
MD #147762 included in kit MD #167693.
If the
AUXILIARY LTS (red) wire is connected to port 87a,
continue on to the next step.
