GMC TRUCK WIRING DIAGRi

ALL MODELS BUILT AFTER AUGUST 22, 1966 GMC TRUCK & COACH DIVISION GENERAL MOTORS CORPORATION Pontiac, Michigan

X-6705

INTRODUCTION This booklet contains Wiring Diagrams for GMC Trucks built after August 22, 1966.

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 three groups in the following order: “Gasoline Engine Models,” “Toro-Flow Diesel Models,” and “Series 53 and 71 Diesel Models.”

NOTE: Two Diagrams (MD-96294#1 and MD-96294#2) do not appear in the index. These are schematic diagrams of the internal electrical circuits of electrical units used as standard and R.P.O. equipment on GMC Trucks.
