6. Installation of the IST Ignition Module and Wiring Harness Adapter:

The Wiring Harness Adapter (See Picture 8, below) is a one-piece assembly consisting of the following connectors:

(a) IST Ignition Module Connector: 32-Socket, Gray (Delphi®/Packard®) - Connects to the S&S® Intelligent Spark Technology Ignition

Module.

(b) Motorcycle Main Harness Connector:

8-Socket Black (Deutsch) – Connects to the stock wiring harness in place of the stock module.

2-Socket black (Delphi®/Packard®)

(d) Knock Sensor Connector:

2-Socket black (Bosch)

(e) MAP Sensor Connector:

3-Socket (Delphi®/Packard®)

(f) Coil Harness Connector:

3-Socket black (Delphi®/Packard®)

(g) Crank Position Sensor Connector:

2-Socket black (Deutsch)

(h) Data Link Connector with Plug:

4-Pin gray (Deutsch)

NOTE: Locking tabs on each connector listed should produce a light click sound when properly assembled. Check each connection by lightly pulling on
each half of the connector to insure that the locking tabs have properly seated.

The IST ignition module includes a hardware packet. The hardware is intended for spacing the module and the connector off of the mounting

backplate. Washers are also included for the mounting screws. This hardware is only necessary on some models. The hardware packet
includes the following spacers and washers:

• .200" Spacers (2)

• .060" Spacers (4)

• .475" O.D. Washers (2)

• .250 I.D. Lockwashers (2)

a. Route the wiring harness along the bike frame to ensure that the Ignition Module Connector (a) (See Picture 8, above) reaches the

Module mounting location.

b. Connect the Ignition Module Connector (a) (See Picture 8) to the Module.

c. Install the module using the stock mounting hardware and the S&S® hardware (if necessary) included with the module.

d. Plug the 8-pin black plug from the stock wiring harness into the black 8-socket Motorcycle Main Harness Connector (b) on the S&S

harness. See Picture 8. (If the motorcycle plug has only seven pins see step B-7.)

e. The portion of the harness that connects to the Head Temperature Sensor, MAP Sensor, and the Knock Sensor should be routed along

with the stock wiring under the gas tank.
