Introduction

Do not perform any procedure in this Special Instruction until you read this information and you understand this information. This Special Instruction is intended for the installation of the 257-4183 Injector Wiring Harness Kit . The 257-4183 Injector Wiring Harness Kit can be used to repair fuel injector connectors.

Removal of a Faulty Connector from the Wire Harness

The following steps can be used in order to remove a faulty connector for an injector on the wire harness that is located under the valve mechanism cover.

1. Identify the connector that needs to be replaced. Wiring for the injector solenoid is not sensitive to polarity.

2. Cut wire (1) at a distance of 70 mm (2.8 inch) from the rear surface of the connector.

3. Cut wire (2) at a distance of 65 mm (2.6 inch) from the rear surface of the connector.

Note: The wires on the old connector are cut to length so that the wires on the wire harness will match up to the new connector. Cutting the wires to the proper length will aid in matching the harness wires to the wires on the new connector.

4. Discard the old connector.

Installation of a New Connector

The following steps can be used in order to install a new connector for an injector on the wire harness that is located under the valve mechanism cover.

1. Use Tool (A) in order to remove 5 mm (0.2 inch) of the plastic from wires (3) and (4) .

2. Use heat shrink tubes (5) from the 257-4183 Injector Wiring Harness Kit . Slide the heat shrink tubes toward the connector in order to expose the butt splices.

3. Insert wire (4) into butt splice (6) .

4. Insert wire (3) into butt splice (7) .
