WIRE FUNCTIONS

Power Leads

The two heavy gauge wires (14 gauge) that deliver battery voltage to

the ignition:

Heavy Red Connects directly to the battery positive (+) terminal

or to a positive battery junction. It could also be con-

nected to the positive side of the starter solenoid.

NOTE: Never connect this wire to the alternator.

Heavy Black Connects to frame or chassis ground.

Trigger and Coil Leads

Small Red Connects to a switched 12 volt source, such as the

ignition key.

Orange Connects to the positive (+) terminal of the coil.

NOTE: This is the only wire that makes electri-

cal contact with the coil positive (+) terminal.

Small Black Connects to the negative (–) terminal of the coil

NOTE: This is the only wire that makes electri-

cal contact with the coil positive (–) terminal.

tion Control: a points circuit (white wire) or a mag-

netic pickup circuit (violet and green wires).

NOTE: The two circuits will never be used

together.

White Connects to points, electronic ignition amplifier out-

put or to the green wire of a Mallory timing acces-

sory. When this wire is used, the magnetic pickup

connector is not used.

Violet/Green These wires are routed together in one harness to

form the magnetic pickup connector. The connector

plugs directly into a Mallory distributor or crank trig-

ger. It will also connect to factory magnetic pickups

or other aftermarket pickups. The violet wire is posi-

tive (+) and the green is negative (–). When these

wires are used, the white wire is not used. Consult

the chart that shows the polarity of other common

magnetic pickups

Yellow Connects to the tachometer pickup wire.

DIAGNOSTIC

LED

MISCELLANEOUS INFORMATION

Sealing

allow any moisture that seeps in through the grommets to drain and

may result in corrosion.

Welding

on the vehicle, disconnect the positive (red) and negative (black) power

disconnect the tachometer ground wire as well.

Distributor Cap and Rotor

As with any high performance ignition system, we recommend install-

Ignition Control. Be sure the cap is clean inside and out, especially the

terminals and rotor tip.

Behind this hole is a red LED indicator. The LED will flash when re-

ceiving a proper trigger signal from the vehicle. If, after a normal power-

up, the LED doesn’t flash when cranking the engine, you should check

your triggering circuit for problems. If the LED flashes when the en-

gine is cranked, but there is still no spark, the problem lies some-

where else.

MOUNTING

you mount it in the engine compartment, keep it away from moving

objects and heat sources. Do not mount the unit in a closed area,

such as the glovebox.

When you find a suitable location to mount the unit, make sure all

wires of the ignition reach their connections. Hold the ignition in place

and mark the location of the mounting holes. Use a 1/8" drill bit to drill

the holes. Use the supplied self-tapping screws to mount the box.

WIRING

Wire Length

as long as quality connectors are used or soldered in place. To lengthen

the wires, use one size larger gauge wire (12 gauge for power leads,

16 gauge for all others). Use the proper connectors to terminate all

wires. All connections must be soldered and sealed.

Grounds

A poor ground connection can cause many frustrating problems. When

a wire is specified to go to ground, connect it to the chassis. Always

connect a ground strap between the engine and chassis. Connect

any ground wires to a clean, paint-free metal surface.

Ballast Resistor

If your vehicle has a ballast resistor in line with the coil wiring, it is not

trol receives its main power directly from the battery.
