INSTALLATION INSTRUCTIONS
FORM 1064 (REV. D) 09/04
GENERAL INFORMATION
Check the ignition coil application to be sure it is being
used in the proper application for optimum performance.
Spark Plug Wires and Coil Wire
To prevent false triggering and possibility of premature
ignition failures, use suppression type spark plug wire.
We recommend spiral core ignition wire, such as Mallory
PRO SIDEWINDER
® 8MM Suppression Ignition Wire or
carbon core ignition wire, such as Mallory PRO WIRE ® 8MM
Suppression Ignition Wire or Mallory SPRINT WIRE ® 8MM
Suppression Ignition Wire.
If your coil wire will not reach between the distributor cap
and the ignition coil, we suggest using one of the Mallory
Spark Plug Wire Replacement Kits. The Mallory Spark Plug
Wire Replacement Kit is a 4 ft. length of 8mm Silicone
Jacketed Suppression Wire assembled with a straight spark
plug boot and terminal on one end, and a 90° spark plug
boot and terminal on one end. Supplied with male (HEI), and
female socket type distributor boots and terminals that make
these kits ideal for remote mounting an ignition coil.

Spark Plug Gaps
For street applications, use your engine manufacturer’s
specifications. For racing applications, start with your
engine manufacturer’s specifications, then experiment
with and closely monitor various gaps to achieve
maximum performance.
MOUNTING PROCEDURE
Ignition coils should be mounted on a flat surface as close
as possible to the distributor and away from extreme heat
from engine components. DO NOT mount ignition coils
to the engine.
Step 1
PROMASTER ® Ignition Coils may be mounted at any angle.
Find a suitable flat surface to mount the ignition coil.
Step 2
Center punch the mounting pattern using the ignition coil
bracket as a template to mark locations for drilling holes.
Drill holes using a 9/64" drill bit.
Step 3
Mount the ignition coil bracket using three #10 x 3/4"
screws.
Step 4
Slide the ignition coil into the ignition coil bracket.
Mount the ignition coil in the ignition coil bracket with the
#10 x 1" screw.
COIL WIRE INSTALLATION
Step 1
Strip 5/8" of insulation from the coil wire. Fold the core over
the outside of the coil wire.
Step 2
Put the coil wire terminal on the end of the coil wire and
crimp the connection.
Step 3
Slide the coil wire into the coil wire boot. Install the coil wire
on the high voltage terminal. See Figure 1.
WIRING PROCEDURE
See pages 2 and 3 for wiring diagrams and information.
NOTE: If you are using an aftermarket ignition control,
such as a Mallory HYFIRE
® Ignition Control or similar,
follow the wiring instructions included with your ignition
control box.
