Introduction

Difficulties are being reported for reconnecting the wire harness to the solenoid valves on certain work tools. Once the connector plugs of the wiring harness are disconnected from the connector plugs of the solenoid, there is no identification on the solenoid in order to match the solenoid valves to the connector plugs on the wiring harness. These instructions provide the necessary information in order to complete the connections.

Do not begin installation until you have read the information that is contained in this instruction. Study the Operation and Maintenance Manual and the Service Manual before begining any service procedures on these work tools.

Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools in order to perform these functions properly.

( 1 )	Do not use this wire harness on Series B machines.
( 2 )	This wire harness is used in conjunction with 225-8014 Work Tool Harness As .

225-8015 Work Tool Harness As

Illustration 1	g01098212

Use on work tools with standard flow

225-8014 Work Tool Harness As

Illustration 2	g01098218

Use on work tools with high flow

Note: There is a jumper wire between terminal "F" and terminal "G" on the 172-3998 Plug As . This wire allows the machines that are equipped with high flow hydraulic systems to provide high flow operation.

166-0294 Work Tool Harness As

This harness was used on work tools prior to the release of Series B machines. The wiring harness has been cancelled. The wiring harness has been replaced by 225-8015 Work Tool Harness As or 225-8014 Work Tool Harness As .
