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.
