COIL LOCATION AND MOUNTING

1. Find a suitable mounting location for the Coil
and Driver assembly. It can be mounted in any
position as long as it is away from direct engine
heat sources. Also make sure that the Coil Driver
wiring harness reaches the distributor.

2. Ensure that there is enough room to clear the Coil
and the Coil Driver when they are assembled.

3. Use the Coil or Driver as a template and mark
the mounting holes. Figure 1 also provides a
template to assist in the mounting.

4. Use a 3/16" drill bit to make the mounting
holes.

2 INSTALLATION INSTRUCTIONS

ASSEMBLE THE COIL AND DRIVER

1. Position the Coil Driver, PN 6305, under the
Blaster SC Coil with the aluminum base facing
down (Figure 2).

2. Install the long Phillips screws through the coil
and into the supplied vibration mount at the
base of the Coil Driver.

3. Mount the Coil/Driver assembly.

WIRING

Primary Wires: The two primary wires, Red and
Orange, are the only wires that connect to the
coil. Orange connects to Coil Negative (-), Red
connects to the Coil Positive (+) terminal. Install
a lock washer followed by the wire terminal with
another lock washer and the supplied Phillips
screws.

Distributor Connector: Route the 4-pin Deutsch
Connector to the mating connector on the
distributor (Figure 3).

Tachometer Output: The Blue wire that is routed
with the distributor connector provides a 12 volt
square wave tachometer output signal. It can be
used for aftermarket tachs, rpm switches and
other accessories (Figure 3).

Note: Vehicles equipped with OEM tachometers

do not require any special wiring for the tach
to operate.
