This document is page 112-4 of the 1995 Ford Bronco factory electrical/wiring reference, covering the Anti-Theft system. It shows connector face views for the two Anti-Theft Controller Module connectors, C237 (pins 1–7 and 15–20) and C238 (pins 8–14 and 21–26), with wire circuit numbers and color codes labeled at each cavity. A complete pinout table lists all 26 pins with their circuit numbers, wire colors, and functions: battery voltage (171 BK/W), headlamps enable output (13 R/BK), liftgate jamb switch input (627 BK/O), run/accessory power (182 BR/W), disarm input (25 DG/P), unlock doors (118 PK/O), unlock driver's door (163 R/O), lock doors (117 PK/BK), key cylinder input (936 DG/W), ignition input (32 R/LB), alarm indicator (343 DB/LG), courtesy lamps input (24 DB/O), horn enable output (1 DB), exterior lamps output (14 BR), grounds (875 BK/LB), and starter motor output (342 LG/P). Several pins (5, 11, 15, 19, 20, 25) are marked NOT USED. A reader can use this page to identify each wire at the anti-theft module for diagnosis, testing, or aftermarket alarm integration on a 1995 Bronco.
