Test the Fuse ByPass Switch by checking that when the button on the top of the Fuse ByPass Switch
is in the
drive position that the car dash lights and functions operate the same as they did before.
With the car engine and key turned fully off, flip the Fuse ByPass Switch to
the
tow position.
All lights and operations that are controlled by the fuse in this circuit should
be off. This mimics the fuse being removed from the fuse panel when towing.
If the Fuse ByPass Switch operates as expected, continue, if not, please
reference the Troubleshooting section.
5. Remove the Fuse ByPass Switch connectors and adapter if supplied, from the fuse box. Note
which terminal the red connector was installed in.
6. Select one of the methods below to route the wiring out of the fuse panel.
Method A
a. Measure from the end of the fuse panel to the center over the
removed fuse terminals. Write down the dimensions.
b. Measure from the side of the fuse panel to the same location over
the removed fuse terminals and write down the dimension.
c. Properly orient the fuse panel cover over the fuse panel and mark
the two dimensions on the cover of the fuse panel.
d. Drill a 5/8” hole at the intersection of these dimensions use a flat power auger.
Method B
a. Alternatively drill a 5/8” hole at the top, left corner of the cover using a flat power auger.
7. Feed the Fuse ByPass Switch terminals through the hole insuring
that the black loom extends from the hole.
8. Reinstall the connectors and replace the cover making sure it
locks on using the plastic tabs.
9. If a Mini Fuse ByPass Switch must be installed, it should be
located at the lower, center of the top cover. Reference the dotted lines in the images shown
above.
Note: this requires a 3/4” hole and the drive position has the white dot side of the switch
depressed when driving the vehicle and the tow position has the black (unmarked side)
depressed when towing. This is opposite of the High Current Fuse ByPass Switch. Install the
labels supplied with the white dot on the switch matched to the drive label.
