This is page 42-7 of the 1994 Ford Bronco/F-Series Electrical & Vacuum Troubleshooting Manual (EVTM), covering the Anti-Lock Brakes (ABS) system. The page shows the C119 4WABS (four-wheel anti-lock brake system) Control Module connector for the Bronco: a 40-pin connector illustration with pin locations numbered 1–40 (two pin groups have been hand-highlighted in blue and red by the uploader). Below the drawing, a full pinout table lists each pin number, its circuit number and wire color code, and the circuit function — for example pin 1/14 = circuit 530 (LG/Y) Ground, pin 18 = 603 (DG) 4WABS Failure Warning Lamp, pin 20 = 601 (LB/PK) Ignition Feed, pins 21–25 = rear and front wheel speed sensor high/low circuits, and pins 15, 26, 27, 33, 34, 40 = the front/rear dump and isolation valve circuits. A Connector Reference List cross-references connectors C223, C250, C251, C252, C267 and C269 to their diagram cells (34, 60, 60, 60, 34, 149). A reader can use this page to identify wire colors and functions when diagnosing or testing the 4WABS control module harness on a 1994 Bronco.
