Installation Instructions
405-0329 Page 1 of 2 6/25/13
ALWAYS match the amperage of the fuse in the Fuse ByPass Switch harness
to the fuse removed from the fuse panel.
NEVER install a fuse with more than a 20 amp rating in the Fuse ByPass
Switch harness .
REMOVE any fuse from the Fuse ByPass Switch harness.
BEFORE YOU BEGIN: Consult the Owner’s Manual for the towed vehicle to
determine which fuse(s) must be removed from the “towed” vehicle and their
location. Most vehicles will require another Fuse ByPass Switch to be installed
under the hood. Confirm that the silver pins on the Fuse ByPass Switch wires
match the pin sizes on the fuses you are required to remove. You must have the correct fuse wire ends for the fuse
holder in the tow vehicle. The Fuse ByPass Switch is designed to control two (2) ATC/ATO blade fuses found in the wiring
located under the passenger rear floor area in the battery compartment.
The Fuse ByPass Switch is designed to be mounted in the upper rear of the floor console beside the power outlet. If the
vehicle is equipped with the optional audio/video connections, then the switch should be mounted below these connectors
on the rear panel of the console. The wiring will flow down behind the console rear panel, then fed under the floor carpet
to the under floor battery compartment and make connection with the two fuse holders found in the wiring.
1. Remove the battery compartment cover using a T20 Torx to loosen (but do not
remove) the screw, then lift the side where the screw is and pull the cover towards the
outside of the car. You may find that removing the plastic floor panels closer to the rear
seat in this area will allow easier removal of the cover. Those panels are in sections
and can be carefully pried up to give the required access.
2. Locate the two (2) fuses which will be taped onto the red battery cable. Remove these
fuses noting which fuse fits in which holder (if they are not the same color and rating).
3. Next remove the bezel surrounding the power outlet. Pry it out carefully by gripping
around the edges and pulling straight back until the retaining clips release.
4. Remove the rear panel of the console using your fingers at the bottom and sides
where the side panels meet the rear panel and carefully pull out the panel. The rear
panel is attached by push pins near the top and bottom on the side
panels. The upper corners also have tabs that fit under the top section of
the console. Gently pry until the rear panel comes loose and disengage
the upper tabs to remove completely remove the panel.
5. Select a location (typically in the middle of the power outlet panel) and
carefully drill a ¾” diameter hole in the plastic panel using a flat power
auger. Avoid drilling into or damaging any nearby wiring. Ensure that you
can reach the back of the Fuse ByPass Switch to install the mounting
nut and to reattach the wires. If the vehicle has the optional audio/video
connectors then the switch can be mounted on the rear panel below these connectors. You will need to remove a
small portion of the sound deadening material to clear a space for the switch.
6. Remove the four (4) wires from the switch by carefully and firmly pulling on the each connector one at a time. Note:
The wiring is in two (2) pairs.
7. Place the switch in the drilled hole, with the four (4) terminals at the bottom and the blank
space on the rear of the switch at the top, to properly orientate it. Install the mounting nut with
the serrated side towards the panel and hand tighten it. Note: When the switch is in the OFF
position, the bottom of the switch button is depressed as shown.
8. Do Not connect the wiring to the fuse holders until this step is completed. Feed the switch end
of the wire under the carpet from the battery compartment so that it exits under the console where the carpet has an
opening. Carefully pull the wiring though the opening to provide enough length to make the connections to the switch.
