Introduction
This Special Instruction is intended for the installation of the 257-4183 Unit Injector Wiring Gp Harness Kit for Injector Kits 20R-6731, 20R-6732, 20R-6733, 20R-6734. Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.Important Safety Information

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 to perform these functions properly.Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard.Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive. If a tool, a procedure, a work method, or operating technique that is not specifically recommended by Caterpillar is used, ensure that it is safe for you and for other people to use.

Failure to follow the instructions or heed the warnings could result in injury or death. Contact your Caterpillar dealer for replacement manuals. Proper care is your responsibility.
Personal injury or death can result from improper assembly procedures.Do not attempt any assembly until you have read and understand the assembly instructions.
Accidental engine starting can cause injury or death to personnel working on the equipment.To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system.Place a Do Not Operate tag at the Start/Stop switch location to inform personnel that the equipment is being worked on.
