INSTALLATION
1. Turn off the ignition switch and disconnect the
battery ground cable before proceeding.
2. Refer to Figure 1. Remove gear case cover plate
and mounting hardware. You may have to drill out
two rivets that hold the cover (reassemble with
supplied self-threading screws). Remove the
sensor plate or breaker points. Make sure that the
correct H-D
 P/N 32402-83 timing rotor is installed.

3. You can completely remove the OE ignition
harness and external module (1980 and later
models) if desired. However, you must disconnect
all OE wires from the coil except the white/black
wire from the engine stop/run switch.
4. Install the Zipper's ignition unit. Wrap one turn of
electrical tape around the end of the protective
wire harness sleeve. This will compress the sleeve
and allow you to easily feed it through the cable
exit hole in the gear case cover. The tape will also
keep the sleeve end from fraying. You will have to
enlarge the hole with a drill on early models and
some Sportsters
 .
5. Rotate the unit and then place it into position as
shown in Figure 2. Be careful to avoid damage to
the black plastic Hall effect sensors on the bottom
of the unit.

6. Route the wiring harness along the side of the unit
and install the mounting standoffs as shown in
Figure 3. Do not fully tighten the standoffs or install
the outer cover plate until after the static timing
procedure.
7. Route the wire harness along the frame tubing to
the ignition coil. Make sure that the harness is
clear of hot exhaust areas and cannot chafe
against sharp edges. Secure the harness with
nylon cable ties.
