RING TERMINAL CONNECTORS:

Furnished with the HYFIRE® 6.6 Electronic Ignition

Controls are two Ring Terminal Connectors for the

convenience of getting a neat installation when the

HYFIRE® 6.6 Electronic Ignition Control is added to an

existing ignition system. These Ring Terminal Connectors

allow the existing ignition system wiring to remain in the

area of the ignition coil.

• Move wires onto the stud that is inside the Ring Terminal

Connector body.

• Secure these wires to the stud with the nut and washer.

• Install the Ring Terminal Connector cap.

(2c) Wiring Method without adapters for Magnetic

Pickup Trigger Pulses (Non-Computer Type); Magnetic

Pickup Distributors or Crank Trigger Ignition

Connecting to Magnetic Pickup Distributors and Crank Trigger

Ignition – Refer to Figure 17.

• Connect the magnetic pickup (+) wire to the SMALL

GREEN WIRE from the HYFIRE® 6.6 Electronic Ignition

Control.

• Connect the magnetic pickup (–) wire to the SMALL

BLACK WIRE from the HYFIRE® 6.6 Electronic Ignition

Control.

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.

• Connect the RED WIRE to the 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. Use a Ring Terminal Connector 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.

• 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.

Step 3

Tachometer Operation:

If a tachometer is used, connect tachometer ignition

sensing lead to the TACH terminal on the HYFIRE® 6.6

Electronic Ignition Control.

If the tachometer does not work after being connected to

the TACH terminal, connect the tachometer ignition sensing

lead to the GREEN WIRE from the Ignition Control Harness.

If this does not work, your tach is a high voltage trigger

tach and will require the Mallory Fuel Injection and

Tachometer Adapter Part No. 29074 or 29078 to supply the

proper signal for the tachometer to operate.

BYPASS CONNECTOR

The Bypass Connector (standard ignition bypass) fits into

the mating plug of the Ignition Control Harness to convert

back to standard ignition. If you use the Bypass Connector,

use ignition ballast resistors designed for the particular

distributor and coil in the wire from the ignition switch. Use

the Power Plug to convert back to standard ignition. Also, if

you are using a Mallory Fuel Injection/Tachometer Adapter

(Part No. 29074), disconnect it (and its diode if used) as

part of converting back to standard ignition. The Bypass

Connector (standard ignition bypass method to convert

back to standard ignition) does not work with magnetic

pickup distributors or crank trigger ignition.

Step 4

Secure all wires with cable ties to prevent contact extreme

heat, sharp objects or moving devices such as fans, belts

and linkages.

Step 5

Recheck all wire and connections to ensure they are

correct before applying power.

Step 6

Connect the battery (–) terminal cable. Start engine and

check operation of the ignition system.

Ignition Control Operation and Features

Mallory HYFIRE® 6.6 686M CD Ignition System

The features of the Mallory HYFIRE 6.6 Ignition System are

controlled by using the hand held controller. The “Mode”

key controls which feature is being adjusted and the value

is changed by using the up and down arrow keys. To use,

simply connect the cable provided between the controller

and the main unit. When finished, you can either remove

the cable and controller for safe storage or leave it con-

nected. The features and their mode numbers are listed

below along with appearing on both the controller and the

main unit.:

RPM Limiting Modes 1, 2, and 3- Utilize in sequence.

Mode 1 – This is the normal engine protection RPM limit. It

is active if no other RPM limit is selected. The range of this

limiter is 1000 to 12800 in steps of 100 RPM.
