Note: The Modified Cap is designed so that you can remove the stock internal coil, and use a higher output
external coil. The stock internal coil MUST be removed before the installation of this cap. Failure to
do so will cause damage to the MSD cap.
Note: Spark plug style, 90° terminals are required
with this MSD cap.
INSTALLATION:
1. Mark the location of each plug wire on the
distributor cap, then remove the wires. Remove
the stock distributor cap, rotor and dust cover.
2. Locate the coil wires and note their color and
location. On the majority of Honda or Acura
engines, the Black/Yellow wire is positive. The
coil negative wire is generally White/Blue, Blue,
Green/Yellow or Green. In some cases, the coil
itself is marked negative (-) and positive
(+).
Note: If you have a question as to the wires’
polarity, use a volt-meter and probe
each wire with the ignition key turned
to the On position. Coil positive will
show 10-12 volts.
3. Once you determine the polarity of the
coil wires you will need to extend the
wires to reach the MSD external coil. Cut
the factory terminals off and solder them
to 14-gauge wiring. Seal the soldered joint
with shrink sleeve or electrical tape.
4. Depending on the model of distributor
you have, you may need to drill a hole
in the new cap to route the wires out. In
some applications the factory rubber
seal is thick enough to cut and slide the
new wires out.
