BASIC WIRING PROCEDURE

Step 1

Refer to Figure 2

Ensure that your vehicle is equipped with a ground cable

between the engine block and firewall (10 gauge or larger

is required). Locate the harness with the LONG RED WIRE

and one LONG BLACK WIRE at the end plate of the

HYFIRE® 6.6 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.

• Plug into 2-pin connector with red and black wires

coming from the end plate on the HYFIRE® 6.6.

• Connect the Ignition Control Harness to the Ignition

Control Plug at the end plate of the HYFIRE® 6.6

Electronic Ignition Control.

Step 2

Choose one method listed below for wiring the HYFIRE®

6.6 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® 6.6 Electronic Ignition Control

into newer vehicles. These adapters and harnesses allow

you to connect the HYFIRE® 6.6 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 3, 4, and 7 when connecting to GM HEI

Systems; Figure 5 when connecting to Late Model GM

HEI/EST Systems; Figure 6 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.
