Blue Ox TC35270 - Manual (Page 4)

A. Route the two-wire harness from the TruCenter up to the motor home’s front hood area. Locate a keyed 12-
volt power source and a ground point.
CAUTION:
Leave enough slack in the wire to allow for axle movement and ensure that a 12-volt circuit is used.
B. Locate a convenient place on the dash or side control panel to mount the TruCenter switch. The switch
should be in a location easily accessed by the driver. Place the small TruCenter decal next to the switch
(room permitting) for identification.
C. Locate a convenient location (out of sight) close to where the switch will be installed. Mount the solid-
state timer relay at this location using a zip tie or ¼” self-tapping screw. If mounting the relay with a screw,
make sure you know what you are drilling into. Next, run the black and red TruCenter wires up to the relay
mounting location. Cut the red wire at a length necessary to reach the relay. Crimp on a female terminal
connector. Plug the red wire onto the N.C. terminal on the relay.
D. Identify a suitable ground. Ground both the black wire going to the TruCenter solenoid and the negative
power input terminal on the relay. Use the necessary connectors supplied to do this.
E. Using the extra red wire and the in-line fuse connector, tie into a keyed 12-volt power source. Connect
the opposite end onto one side of the switch. Using the remaining red wire, plug into the open terminal
of the switch. On the opposite end, create a small pigtail and plug into the positive power input and COM
terminals on the relay.
F. Insert 15-amp fuse. Lastly, test the solenoid by supplying power, bumping the switch and listening for the
“click”.
