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.
Trigger Wires Either of two circuits will trigger the HYFIRE
®
VIA
Ignition 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.
ROUTING WIRES
Route all wires away from heat sources, sharp edges, and moving
objects. Route the trigger wires separate from the other wires and
spark plug wires. If possible, route them along a ground plane, such
as the block or firewall, which creates an electrical shield. The mag-
netic pickup wires should be routed separately and twisted together to
help reduce extraneous interference.
WARNING: The HYFIRE
®
VIA Ignition Control is a capacitive dis-
charge ignition. High voltage is present at the coil primary termi-
nals. Do not touch these terminals or connect test equipment to
them.
PRESTART CHECKLIST
 The only wires connected to the coil terminals should be the or-
ange connected to coil positive (+) and black connected to coil
negative ().
 The small red wire is connected to a switched 12 volts source,
such as the ignition key.
 Power leads are connected directly to the battery positive and nega-
tive terminals.
 If youre not using an alternator, the battery should be connected
and fully charged.
 The engine is equipped with at least one ground strap to the
chassis.
THEFT DETERRENT
The HYFIRE
®
VIA Ignition Control provides an easy way to install a
theft deterrent kill switch. See Figure 2.
White Wire Trigger
When using the white wire to trigger the HYFIRE
®
VIA Ignition Control,
install a switch across the magnetic pickup violet wire to ground. When
the violet wire is grounded, the vehicle will crank but will not start.
Magnetic Pickup Trigger
When using the mag pickup to trigger the HYFIRE
®
VIA Ignition Control,
install a switch to the white wire and the other side to ground. When the
white wire is grounded, the vehicle will crank but will not start.
