Step F
Install the motorhome monitor LED
Note: there are two lengths of black wire in this kit,
each with a female bullet connector at one end. Use
the long length of wire in this step.
Note: some motorhomes are manufactured with aux-
iliary wires pre-strung from the rear of the motorhome
to the dashboard, for aftermarket accessories such as
this. Call the manufacturer.

Attachthe connector withoneormore of the in-
cluded wire ties. Allow enough slack so that a male

Note: in Step C, you may have chosen to use
open terminals on the electrical sockets to connect the

monitor wiring between the two vehicles. If this is the
case, cut the female bullet connector off, and attach
the monitor wire to the open terminal on the motorhome
electrical socket.

sideofthedashboard.Avoidlines,hoses,movingparts
(slideouts, sliding generators, sliding battery trays) or
“hot” components such as exhaust systems. Where
appropriate, use wire ties to secure the wire to the
undercarriage.

Step G
Test the braking system
Note: the motorhome and towed vehicle must be
stationary for the system test, and ready for towing —
all components of the braking system must be properly
connected and receiving power. Then, according to the
manufacturer, make all adjustments necessary to pre-
