No. 22372 2 May 1998. INTRODUCTION EARLY REVISION VEHICLE HARNESSES.

6 The purpose of this book is to provide the trained All 9- and 12-pin vehicle harnesses are labeled mechanic with a comprehensive reference to with a white tag indicating the harness part assist in diagnosis and repair of FISHER number and revision level. Early 9-pin harness Minute Mount snowplow Electrical systems. It revisions 1-9 and 12-pin harness revisions 1-7. contains Schematics , diagrams and charts which have a ground circuit in which the control, motor supply information for the various types of vehicle relay, and Headlamp relays all ground through the and plow Headlamp systems. Although intended 9- or 12-pin connector.

7 Some of these early primarily as a diagnostic tool for Headlamp revision harnesses also have a diode in the systems, the Straight blade hydraulic system ground wire to the Headlamp relays. Complete 9- circuitry is also included to show the complete and 12-pin system Schematics showing this early Electrical system. revision ground configuration are included in the front of the book . These Schematics are for early HOW TO USE THIS book revision harnesses using only the solenoid Use the information in the Table of Contents to control. If a hand-held control has been installed, locate the Electrical schematic for the vehicle.

8 All the ground circuit has been modified into the later Headlamp harnesses are tagged with the harness revision configuration, in which only the Headlamp part number. The schematic is an abstract relays ground through the 9- or 12-pin connector drawing showing the purpose of each component and the control and motor relay ground separately in the system. Where possible, component to the battery. Early revision harnesses may be locations are indicated by enclosures on the easily identified by a single black/orange wire on schematic. The Lamp Type, Wire Color and one of the motor relay primary terminals which Connector Identification charts and diagrams will does not continue on to the negative battery give specific wire colors, their function and terminal.

9 All vehicle side Schematics in this book locations in connectors. Any special notes are show only the later revision circuitry. found in the upper right corner of the schematic. Further information and a specific troubleshooting NOTE: To verify the correct light kit/plug-in guide may be found in the Mechanic s Guide for harness on a particular vehicle, refer to the the SEHP system. appropriate Kit Selection Guide. The 9- and 12-pin Vehicle Side Schematics contain all vehicle Headlamp and harness types. The 7-pin Vehicle Side Schematics show only a few representatives applications. For other 7-pin vehicle Headlamp and harness types, refer to the corresponding 9-pin Vehicle Side schematic and use only the Headlamp circuitry.
