INSTALLATION INSTRUCTIONS
UNILITE
®
ELECTRONIC BREAKERLESS CONVERSION KIT
FOR MALLORY POINT DISTRIBUTORS
NOTE: This product is legal in California only for racing vehicles which may never be operated upon a highway.
IMPORTANT
All kits listed below must be used with an ignition ballast resistor (or loom resistance wire) to prevent
module failure. If your vehicle is not equipped with a ballast resistor or loom resistance wire, Mallory
Ballast Resistor (Part No. 700) may be used.
These kits do not work with vacuum advance distributors.
APPLICATIONS
Part No. 558
Mallory 8 cylinder point distributors
(automotive and marine) which use
a standard stack cap (Part No. 209
or 209D)
Mallory 8 cylinder point distributors
(automotive and marine) which use
a flat cap (Part No. 221 or 221B)
Mallory 6 cylinder point distributors
(automotive and marine) which use
a standard stack cap (Part No. 270
or 270B)
Mallory 6 cylinder point distributors
(automotive and marine) which use a
mini bowl cap (Part No. 226 or 226B)
Mallory 4 cylinder point distributors
(automotive and marine) which use
a standard stack cap (Part No. 271
or 271B)
Mallory 4 cylinder point distributors
(automotive and marine) which use a
mini bowl cap (Part No. 225 or 225B)
WARNING
You must install the UNILITE
®
Conversion Kit
exactly as shown in these instructions. After the
kit is installed—and
before you start the engine—
check all wiring again. Mis-wiring will cause the
UNILITE
®
Ignition to fail immediately.
Part No. 559
INSTALLATION
Step 1
Remove the cap and rotor, then remove the con-
denser. Remove the plastic insulators (see Figure 1).
Step 2
Loosen the 2 nuts that hold the cap clips/brackets in
place (see Figure 1).
NOTE: To loosen the nuts on a marine distributor,
the aluminum pins in the brackets may need to
be cut in two and removed. Replacement pins
are provided.
Step 3
Remove the point plate assembly by lifting it out of
the housing (see Figure 1).

Step 4
Use a 2-arm or 3-arm puller and the thrust button
(provided) to remove the cam from the rotor sleeve
(see Figure 2).
WARNING: Do not try to remove the cam by
prying on it with a screwdriver(s). This will
damage the advance assembly.
Step 5
Install the UNILITE
®
plate assembly into the housing.
Make sure that the cut-out in the plate is directly
below the hole in the housing where the wires will exit
(see Figure 3).
Step 6
Tighten the two nuts that hold the cap clips/brackets
in place. This also secures the UNILITE
®
plate.
Step 7
Marine Distributors Only
Replace the cap clips using the new aluminum pins
provided.
Step 8
Install the wire grommet. Lubricate the wires with light
oil. Run the wires through the grommet and out of the
distributor housing (see Figure 3).
Step 9
Install the connector onto the wires. Be sure the wires
are in the correct positions (see Figure 4).
Step 10
Install the rotor/shutter wheel assembly. Make sure
that the rotor is fully seated and that it does not rub
the module wires. Replace the cap.
Step 11
If you removed the distributor to install the UNILITE
®
Conversion Kit, reinstall the distributor in the engine.
Step 12
Connect the wire harness to the connector. Connect
the 3 wires to the correct locations, as shown in
Figures 5 and 6.
Step 13
Set the ignition timing. Start the engine and recheck
timing.

NOTE: The purpose of an ignition ballast
resistor between the ignition switch (12V)
and the ignition coil positive terminal is to
restrict current flow through the ignition
coil. Failure to use an ignition ballast
resistor will eventually destroy the Ignition
Module.
EXCEPTION: If your vehicle is equipped
with a HYFIRE

or similar aftermarket ignition control, use
the wiring procedures stated in the instruc-
tions included with the ignition control.

To prevent false triggering and possible
premature ignition failure, you must use
suppression type (carbon core, spiral
core, or radio suppression core) spark
plug wire.
DO NOT USE SOLID CORE (COPPER

SPARK PLUG WIRE WITH ANY
ELECTRONIC IGNITION SYSTEM.

FOR MARINE USE ONLY
After installing your Mallory Electronic Distributor,
the Electronic Shift Assist (ESA) circuit in your boat
must be function tested.Shifting into or out of gear
can be difficult or impossible if the ESA circuit is
malfunctioning or missing. If you encounter shifter
related problems with your boat after installing any
Mallory distributor, contact the Mallory Technical
Service Department at 216.688.8300.
All Mallory Marine Electronic Ignition Systems in
Outboard Marine Corp (OMC) applications with a shift
box require the gray wire from the coil to the shift box
be modified as follows:
The gray wire from the coil (–) terminal triggers
the shift box. The gray wire should be cut or
disconnected at the coil terminal so that the
components shown here can be inserted. Solder
all connections and confirm correct operation,
then insulate well, especially if the boat is being
used in salt water.
