Crown Victoria / Grand Marquis Airbag Crash Sensor & Connector Location Diagram

This document is a Ford/Mercury full-size sedan (Crown Victoria / Grand Marquis) engine compartment component location diagram, viewed from the front of the vehicle, with an A–F grid on both margins. It identifies connector, ground, and component locations including the blower motor (C167), A/C clutch cycling pressure switch (C155), EGR vacuum regulator solenoid (C179), brake pressure switch (C235), crankshaft position sensor (C177), grounds G100–G103 and G101, the relay cluster at G100 (rear defogger, compressor, horn, police power, and cooling fan relays), air suspension compressor motor and vent solenoid (C158), windshield washer low fluid switch (C1021) and pump (C1022), headlamp connectors (C1030–C1033), cornering lamps (C1024, C1025), side marker lamps for the Grand Marquis (C1028, C1029), idle air control (C1003), and the left and right primary airbag crash sensors. The uploader has circled the Left Primary Crash Sensor in green and added the note that it is "located behind highbeam portion of headlamp assembly, underneath the radiator sight shield." A boxed disclaimer states the illustration and grid should not be used for reporting vehicle repair locations. The diagram is useful for locating airbag crash sensors and front-end electrical connectors on these vehicles.
