Connecting the Ignition Control Harness:
• Route the Ignition Control Harness to the ignition coil so
that its wires do not make contact with extreme heat,
sharp objects or moving devices such as fans, belts and
linkages.
• Connect the RED WIRE to the terminal on the ignition
ballast resistor that previously had the DARK GREEN/RED
WIRE connected to it (or to a 12-volt wire from the ignition
switch). NOTE: The RED WIRE must get voltage when the
ignition switch is in the START and RUN positions.
• Connect the YELLOW WIRE to the ignition coil (+)
terminal. DO NOT allow any wire except the YELLOW
WIRE to make contact with the ignition coil (+) terminal.
• Connect the BLACK WIRE to the ignition coil (–) terminal.
• DO NOT connect the GREEN WIRE of the Ignition Control
Harness to anything. Tape the end of it to insulate it.
• Go to Step 3, page 11.

Connecting the Ignition Control Harness
• Route the Ignition Control Harness to the ignition coil so
that its wires do not make contact with extreme heat,
sharp objects or moving devises such as fans, belts and
linkages.
• Disconnect ALL wires located on the ignition coil (+)
terminal. These include the wires from the ignition
switch/ignition ballast resistor, start/ignition bypass and
any other wires normally connected to the ignition coil (+)
terminal. Connect these wires to the RED WIRE. NOTE:
The RED WIRE must get voltage when the ignition switch
is in the START and RUN positions. If you are using a
Mallory Electronic Ignition, connect its BROWN WIRE to
engine ground and add its RED WIRE to the Ignition
Control Harness RED WIRE. Use Ring Terminal
Connectors to join wires together (See page 2 - Ignition
Ballast Resistor / Loom Resistance Wire and Standard
Ignition Bypass).
• Similarly, disconnect ALL wires located on the ignition coil
(–) terminal. Connect these wires to the GREEN WIRE. If
you are using a Mallory Electronic Ignition, add its GREEN
WIRE to the Ignition Control Harness GREEN WIRE. Use
Ring Terminal Connectors to join wires together.
• Connect the YELLOW WIRE to the ignition coil (+)
terminal. DO NOT allow any wire except the YELLOW
WIRE to make contact with the ignition coil (+) terminal.
• Connect the BLACK WIRE to the ignition coil (–) terminal.
• Go to Step 3, page 11.
For coil-in-cap distributors only
Refer to Figure 9 while performing the following steps.
• Connect the BAT PLUG/wire to the RED WIRE.
• Crimp the YELLOW WIRE to the YELLOW WIRE of the
Adapter Part No. 29043 3-pin connector.
• Crimp the BLACK WIRE to the BROWN WIRE of the
Adapter Part No. 29043 3-pin connector.
• Plug the Adapter Part No. 29043 3-pin connector into the
distributor cap.
• Note: DO NOT connect the GREEN WIRE of the Ignition
Control Harness to anything. Tape the end of it to insulate
it.
• Go to Step 3, page 11.
For external coil only
Refer to Figure 11 while performing the following steps.
(Replace the words “spade receptacle terminal” with “ring termi-
nal” when aftermarket coils with post type terminals are used.)
• Disconnect the BAT wire from the ignition coil BAT/(+)
terminal. Connect the BAT wire to the RED WIRE.
• Disconnect the tachometer wire from the ignition coil
TACH/(–) terminal.
• Crimp a spade receptacle terminal on the Ignition Control
Harness YELLOW WIRE. Connect the YELLOW WIRE to
the ignition coil BAT/(+) terminal. DO NOT allow any wire
except the YELLOW WIRE to make contact with the
ignition coil BAT/(+) terminal.
• Crimp a spade receptacle terminal on the Ignition Control
Harness BLACK WIRE. Connect the BLACK WIRE to the
ignition coil BAT/(–) terminal.
• Discard the adapter plug with the yellow and brown wires
from the Adapter PART NO. 29043. It is not used on
external ignition coil HEI systems.
• Note: DO NOT connect the GREEN WIRE of the Ignition
Control Harness to anything. Tape the end of it to insulate
it.
• Go to Step 3, page 11.
Connecting to Mopar/Chrysler Electronic Systems (non-computer
type) using Harness PART NO. 29040 for OEM magnetic pickup
Refer to Figure 13 while performing the following steps.
• Disconnect all connectors at the ignition module, ignition
coil and distributor. Remove the ignition module. Take
notice of a DARK GREEN/RED WIRE connected to the
ignition ballast resistor. Remove the distributor and coil
harnesses.
Connecting the Harness PART NO. 29040:
• Connect the ACCEL 500+ Electronic Ignition Control’s
SMALL GREEN WIRE to the Harness RED WIRE.
• Connect the ACCEL 500+ Electronic Ignition Control’s
SMALL BLACK WIRE to the Harness BLACK WIRE.
• Connect the mating plug of the Harness to the distributor
plug.
