This is page 151-1, "Component Location View," from a Ford factory wiring/EVTM-style manual, scanned from a 1990 Ford Bronco owner's document set. It shows an overhead line-drawing of the engine compartment for the 4.9L engine (sheet 1 of 2), overlaid with a locator grid (columns 1-10, rows A-F). Labeled components include the oil pressure sender, throttle position sensor, EGR valve position sensor, manual lever position sensor, electronic engine control (EEC) module, timing test level, manifold absolute pressure sensor, A/C clutch cycling pressure switch, blower motor, starter relay, engine coolant temperature sensor, TFI ignition module, air charge temperature sensor, daytime running lamps module, both headlamps, and ground G100. Fuse links A, F, G, L, M, N, P, and W are located near the starter relay area. Numerous harness connectors are called out: C101, C103, C106, C110, C118, C122, C128, C143, C151, C154, and C202. A boxed note warns not to use the illustration and grid for reporting vehicle repair locations. The form number FPS-12129-90 (6 of 12) dates the document to 1990. Readers can use this page to locate underhood sensors, modules, relays, fuse links, and connector positions on a 4.9L (300 I6) engine.
