4. Refer to Figure 3 for correct location for
mounting the second eyebolt.
Drill a 9/32-inch hole for the eyebolt. Secure
with two 1/4-inch nuts and two lockwashers.
This eyebolt is necessary so that the pin will be
pulled straight out from the breakaway switch
if the trailer should become disconnected.
5. Insert the breakaway switch disengagement
pin into the breakaway switch.
6. Disconnect the snap hook (it is not
permanently attached) from the chain end of
the lanyard assembly. Save the hook and its
attachment clip.
7. Thread the lanyard, chain end first, through the
eyebolt mounted on the trailer tongue.
8. Determine the correct length for the lanyard.
The lanyard is the correct length if the following
conditions are satisfied:
Condition 1: If trailer should become
disconnected, the lanyard must become
taut and pull the pin out of the breakaway
switch before the trailer safety chains
become taut.
Condition 2: If the trailer should become
disconnected, the lanyard must become taut
and pull the pin out of the breakaway switch
before the towing vehicle-to-trailer electrical
wiring becomes taut. Making the electrical
wires longer than the safety chains is a
convenient way to accomplish this.
Condition 3: During normal towing operation,
the lanyard must NOT become taut enough to
pull the pin out of the breakaway switch when
turning a corner.
Condition 4: During normal towing operation,
either straight or while turning corners, no
chains or wiring should be allowed to drag on
the ground.
Adjust the lanyard to the right length by
removing the individual chain links.
The lanyard, if installed correctly, now extends
from the switch, with the pin inserted into the
switch, through the eyebolt on the trailer
tongue, and attaches to the eyebolt on the
towing vehicle.
9. Leaving the lanyard threaded through the
eyebolt on the trailer tongue, secure the snap
hook to the end chain link. Use pliers to close
the snap hook attachment clip completely
around the end of the snap hook.
10. Fasten snap hook to the towing vehicle
eyebolt.
