GMC TRUCK & COACH DIVISION GENERAL MOTORS CORPORATION Pontiac, Michigan

INTRODUCTION This booklet contains Wiring Diagrams for GMC Trucks built after August 2, 1971.

To determine which diagrams are applicable to a specific truck series, refer to the “Wiring Diagram Index” which follows. For convenience, the index is divided into four groups in the following order: “Gasoline Engine Models,” “GMC (Turbium) Diesel Models,” “Detroit Diesel Models,” and “Cummins Diesel Models.”

NOTE: Five diagrams (T-7305 through T-7309-1) do not appear in the index.

These are schematic diagrams of “Body Builder’s Connections.”

DIRECTIONS FOR INTERPRETING THE NEW ADDRESSING CONCEPT THIS DOCUMENT INCORPORATES A NEW MAPPING CONCEPT TO REPLACE LINES REPRESENTING WIRES. IT READS IDENTICAL TO MOST ROAD MAPS IN THAT NUMERIC STATIONS ARE ASSIGNED HORIZONTALLY AND ALPHABETIC STATIONS ARE ASSIGNED VERTICALLY. THEREFORE ANY COMBINATION OF NUMERIC AND ALPHABETIC CHARACTERS DESIGNATES A PRECISE LOCATION. TO ILLUSTRATE THE USE OF THIS CONCEPT LETS USE THE HORN CIRCUIT. LOCATED IN THE UPPER LEF T HAND CORNER. AS AN EXAMPLE. THE NUMBER 29 CONTAINED IN THE RECTANGLE [ H REPRESENTS THE CIRCUIT NUMBER. IMMEDIATELY TO THE RIGHT APPEARS 12DG. THE NUMBER 12 SPECIFIES THE GAUGE OF THE WIRE AND DG IS THE ABBREVIATION FOR THE WIRE COLOR. DARK GREEN. SHOWN IN PARENTHESIS IS (24C). THIS IS THE ADDRESS IDENTIFYING THE LOCATION OF THE OTHER END OF THE WIRE.TO FIND THIS LOCATION. SIMPLY SCAN THE BOTTOM OF THE SHEET TO THE NUMBER 24 AND THEN SCAN VERTICALLY TO THE APPROXIMATE LOCATION OFC. THE CIRCUIT*^ SHOULD POP INTO VIEW. TO FOLLOW THE CIRCUIT IN REVERSE,SIMPLY REVERSE THE PROCEDURE. FOLLOW THE LEAD IN r, 'RE OUT OF THE RECTANGLE gg) AT THE END OF THIS WIRE APPEARS (4S) 12 DG AGAIN. THE NUMBER 12 REPRESENTS WIRE GAUGE AND DG THE WIRE COLOR. DARK GREEN, fts) IS THE ADDRESS. TO FIND THIS LOCATION, SCAN THE BOTTOM OF THE SHEET TO STATION 4 AND SCAN VERTICALLY TO THE APPROXIMATE LOCATION OF*S’ THE CIRCUIT*^ SHOULD BE IMMEDIATELY APPARENT.
