Connecting the TT150 to the 7-Way
Overview
The power cable is 10 feet long and can be cut as needed depending on the where the TT150
terminal is installed. Whenever possible, use existing holes to route cable into the 7-way. It may
be necessary to drill a hole through the 7-way housing to provide a route for the cable.
Two 3 amp fuses are included for use on the TT150 system power cable blue POWER wire and
brown LIGHTS wire.
Preparing for Connection to the 7-Way
1.
Remove the 7-way receptacle cover from outside the trailer.
2.
If necessary, drill a 7/8" hole into the bottom side of the 7-way box.
3.
As needed, cut the TT150 power cable to an appropriate length, leaving some slack for
making 7-way connections later and securing away from the trailer gladhand/hose
coupler connections.
4.
If a 7/8” hole was drilled into the 7-way box, install the supplied grommet over the
cable and secure into the hole.
5.
Route the power cable into the 7-way box and out the receptacle opening.
6.
Strip 4” from the cable shielding and 1/4” from the wire insulation on the blue, white,
brown, and two gray wires. Do not strip insulation from the green or yellow wires.
