This is page 42-7 from the 1994 Ford Bronco/F-Series Electrical & Vacuum Troubleshooting Manual (EVTM), covering the Anti-Lock Brakes (ABS) system. The page shows the C119 connector for the 4WABS (four-wheel anti-lock brake system) Control Module on the Bronco, with a physical pin-position diagram of the 40-pin connector and a complete pinout table. For each pin, the table lists the circuit number, wire color code, and circuit function — for example, pins 1 and 14 are grounds on circuit 530 (LG/Y), pin 20 is the ignition feed on 601 (LB/PK), pins 21-25 and 36 are the rear, RH front, and LH front wheel speed sensor high/low circuits, and pins 15, 26, 27, 33, 34, and 40 are the dump and isolation valve circuits. Other pins cover the 4WABS failure warning lamp, relay coils, G-switches, motor speed sensor, vehicle speed output, and diagnostic trigger. A connector reference list maps connectors C223, C250, C251, C252, C267, and C269 to their EVTM cell numbers. The scan includes hand-drawn red and blue marks highlighting certain pin groups on the connector diagram. Useful for diagnosing 4WABS wiring, sensor, and valve circuit issues.
