Installation
To install, follow the removal steps in the reverse order,
noting the following point.
1. Push in the switch with your fingers until it locks
securely.

5. The wiring harness between engine and chassis
should be long enough (2). Tension of the wire (1) may
causes chafing or damage due to various vibrations.
Splicing Wire
1. If the harness is taped, remove the tape. To avoid wire
insulation damage, use a sewing “seam ripper”
(available from sewing supply stores) to cut open the
harness.
If the harness has a black plastic conduit, simply pull
out the desired wire.
2. Begin by cutting as little wire off the harness as
possible. You may need the extra length of wire later
if you decide to cut more wire off to change the location
of a splice. You may have to adjust splice locations to
make certain that each splice is at least 1–1/2”
(40 mm) away from other splices, harness branches,
or connectors.
3 . W h e n r e p l a c i n g a w i r e , u s e a w i r e o f t h e s a m e s i z e a s
the original wire.
Check the stripped wire for nicks or cut stands. If the
wire is damaged, repeat the procedure on a new
section of wire. The two stripped wire ends should be
equal in length.
4. Select the proper clip to secure the splice.
To determine the proper clip size for the wire being
spliced, follow the directions included with your clips.
Select the correct anvil on the crimper. (On most
crimpers your choice is limited to either a small or
large anvil.)
Overlap the two stripped wire ends and hold them
between your thumb and forefinger as shown in the
figure.
The center the spline clip (1) under the stripped wires
and hold it in place.
Open the crimping tool to its full width and rest one
handle on a firm flat surface.
Center the back of the splice clip on the proper anvil
and close the crimping tool to the point where the back
of the splice clip touches the wings of the clip.
Make sure that the clip and wires are still in the correct
position. Then, apply steady pressure until the
crimping tool closes as shown in the figure.
