The Universal Switch Box Harness is designed to connect
to your existing boom control switches. The system will
accommodate from one to four boom switches.
Connect the boom harness to the 4-pin M/P connection
on the main harness. Route the cable to the boom control
switches. If more length is needed, extension cables are
available in 5’, 10’, 15’, 20’ and 25’ lengths.
What you want to accomplish is to attach the boom wires
from the MT-2400 harness to the wires on the shut-off valve
harness that are on the solenoid side of the boom switches.
Attach the RED wire to boom 1, the WHITE wire to boom 2,
the GREEN wire to boom 3 and the BLACK wire to boom 4.
See Illustrations 19A and 19B.
Use the moisture resistant tap connectors supplied with the
kit to make the connections.
NOTE: Always turn power to the switches OFF before
installing or removing tap connectors.
