MSD 6 OR 7 SERIES IGNITION CONTROL

The MSD 6 or 7 Series Ignitions receive 12 volts directly from the battery and are responsible

for delivering the positive voltage to the coil. Therefore, a 12 volt source wire is not required

at the coil. When the installation is complete, there will only be two wires making direct

contact to the coil terminals: the Orange wire from the MSD connects to the coil positive

(+) terminal. The Black wire from the MSD connects to the coil negative (-) terminal

(Figure 3).

INSTALLATION INSTRUCTIONS

REPLACING AN E-CORE STYLE COIL

(FORD TFI OR GM DUAL COIL CONNECTOR)

The MSD Blaster Coils can be used in place of your late model e-core style coil. The Ballast

Resistor does not need to be installed in either of these installations.

Ford TFI: Look on the original coil to determine the coil negative and coil positive wires. Coil

positive is usually Red/Lt. Green and negative is generally Dark Green/Yellow. Cut the wires

and install the two female Faston terminals to the wires.

GM Dual Connector Coil: There are four (sometimes three) wires going into the GM Coil.

Two wires are positive and two (sometimes one) are negative. It is important to install each

wire to the MSD Coil. Cut the wires and splice the corresponding polarity wires together and

install the supplied female faston connectors.
