WIRING PROCEDURE
Step 1
Refer to Figure 3
Ensure that your vehicle is equipped with a ground cable between the engine block and firewall
(10 gauge or larger is required). Locate one LONG RED WIRE and one LONG BLACK WIRE
at the end plate of the HYFIRE ® IV Electronic Ignition Control.
• Connect the LONG RED WIRE to the battery (+) post or battery (+) terminal on the
starter solenoid.
• Connect the LONG BLACK WIRE to engine ground or chassis ground.
• Connect the Ignition Control Harness to the Ignition Control Plug at the end plate of the
HYFIRE ® IV Electronic Ignition Control.
Step 2
Choose one method listed below for wiring the HYFIRE ® IV Electronic Ignition Control (2a, 2b,
or 2c)
(2a) Wiring method using Adapters and Harnesses (sold separately)
Special wiring Adapters and Harnesses simplify the installation of the HYFIRE ® IV Electronic
Ignition Control into newer vehicles. These adapters and harnesses allow you to connect the
HYFIRE ® IV Electronic Ignition Control between the ignition coil and the factory coil connector.
They reduce installation time and wiring errors. Also, converting back to the factory ignition is
easy because there is no need to cut the original wiring. These instructions cover:
PART NO. 29042 – Connecting to GM HEI Systems (coil-in-cap, with OEM ignition module)
PART NO. 29068 – Connecting to Late Model GM HEI/EST Systems (external coil)
PART NO. 29062 – Connecting to Ford TFI Systems.
PART NOS. 29039 and 29040 – Connecting to Ford DuraSpark Systems (non-computer
type, without ignition module).
PART NOS. 29040 and 29043 – Connecting to Early Model GM HEI Systems (non-computer
type, without ignition module)
PART NO. 29040 – Connecting to Mopar/Chrysler Electronic Systems (non-computer type,
without ignition module).
Connecting to: GM HEI Systems (coil-in-cap, with OEM ignition module), use Adapter
PART NO. 29042; Late Model GM HEI/EST Systems, use Adapter PART NO. 29068; Ford
TFI Systems, use Adapter PART NO. 29062.
Connecting Adapter PART NO. 29042, 29062 or 29068
Refer to Figures 4, 5, and 8 when connecting to GM HEI Systems; Figure 6 when connecting
to Late Model GM HEI/EST Systems; Figure 7 when connecting to Ford TFI Systems.
• Match wires by color from the Adapter to the Ignition Control Harness. Crimp all wires
together.
• Disconnect the factory harness(es) at the ignition coil. Connect them to the Adapter that has
the RED and GREEN WIRES.
• Connect the Adapter that has the YELLOW and BLACK WIRES to the ignition coil. NOTE:
When using an aftermarket ignition coil with post type terminals, discard the Adapter that has
the YELLOW and BLACK WIRES. Install ring terminals on the Ignition Control Harness
YELLOW and BLACK WIRES. 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 9.
