This document is a single illustrated figure (numbered 16.60) from an automotive service manual showing the mounting location of the early model Ford EEC-IV relay box. The line drawing depicts the left-hand (L.H.) fender apron area of the engine compartment, with callout arrows identifying four items: the RELAY ASSEMBLY, the RELAY AND HOUSING ASSEMBLY, and two WIRING ASSEMBLY harnesses that route into the relay box. The caption states that the early model EEC-IV relay box is mounted in the engine compartment against the left side fender apron, and notes that later models have the relay box in the same location. A reader can use this figure to locate the EEC-IV relay/housing assembly on the driver's side inner fender when diagnosing engine management or relay problems, and to identify the associated wiring harness connections. The page carries a section tab number '4' in the margin, indicating it comes from chapter/section 4 of a repair manual. No fuse values, part numbers, wire colors, or specific model years are printed in this figure; it is purely a component location illustration.
