MSD 6304 Installation
DIS CPC Signal Converter
PN 6304
Parts Included:
1 – DIS CPC Signal Converter
1 – Parts Bag
The MSD DIS CPC Signal Converter wires inline on the factory coil harness. It allows for the installation
of an MSD DIS-4 Series Ignition Control and Coils on vehicles with factory transistorized/driver style
coils. It achieves this by inverting the logic signal from the ECU and creating an output signal designed
to trigger the points input of an MSD DIS Ignition. The PN 6304 will not drive a coil.
Note: There are a number of different applications that can use the PN 6304. These instructions
illustrate a couple different installations. It is recommended to have the wiring schematic of
your vehicle prior to installation.
Coils: MSD recommends the PN 8207 Blaster SS Coil for Coil-per-Cylinder systems or PN 8204
(available from MSD Powersports).
MOUNTING
The DIS CPC Signal Converter is designed to be mounted under the hood. The circuits are potted
in polyurethane for water resistance and vibration protection. Position the unit away from excessive
heat sources and mark the location of the three mounting holes. Use a 5/32” bit to drill the holes and
secure the unit with the supplied screws.
WIRING
Route the wires away from any direct heat sources, rotating components, and sharp edges. The DIS
CPC Signal Converter comes with both male and female bullet terminals installed on the harness.
These terminals are designed to plug directly into the harness of an MSD DIS-4 color to color. The
ring lugs supplied in the parts bag install on the black wires and are to be connected to a good
chassis ground.
