Power window wiring diagram showing window regulator safety relay, master control switch and color-coded motor circuits.
Part of 1992-1997 Ford Crown Victoria Wiring Diagrams
This document is a power window wiring diagram (page 1 of a multi-page set) showing the power feed and master window control switch circuits. Battery power (hot at all times) comes from a fuse in the engine compartment fuse box (page 13-3) through circuit 193 V/LG to the Window Regulator Safety Relay at connector C266 (relay pins 86, 30, 85, 87, 87A). The relay is controlled by the Lighting Control Module (LCM) via circuit 194 PK at connector C221, pin 13 (RELAY OUT). Relay output circuit 400 LB/BK feeds the Moon Roof Switch (via C300F/C300M, page 101-1), splices S217 and S510, connector C522, and the Master Window Control Switch at connector C508. The master switch contains left front, right front, left rear, and right rear window switches plus a window lockout switch, and directs current to the door motors; motor direction depends on switch position. Output circuits with wire colors and destinations are listed: 57 BK ground to G204 via S500; 227 V to S517; 226 W/BK to C522; 314 T/LB and 313 W/V to C606; 170 R/LB to S264; 316 V/LB and 317 GY/O to C706; 320 R/BK and 319 V/BK to C806. Cross-references include power distribution (13-3), grounds (10-11), and LCM (58-4).

Frequently asked questions
- What powers the Window Regulator Safety Relay?
- A hot-at-all-times feed from the engine compartment fuse box (page 13-3) on circuit 193 V/LG, entering the relay at connector C266.
- What controls the Window Regulator Safety Relay?
- The Lighting Control Module (LCM) via circuit 194 PK at connector C221 pin 13 (RELAY OUT); see page 58-4 for the LCM.
- What circuit feeds the master window control switch?
- Circuit 400 LB/BK from the safety relay, through splices S217 and S510, into the master switch at connector C508. The same circuit also feeds the moon roof switch through C300F/C300M.
- What are the wire colors leaving the master window switch?
- 57 BK (ground to G204 via S500), 227 V, 226 W/BK, 314 T/LB, 313 W/V, 170 R/LB, 316 V/LB, 317 GY/O, 320 R/BK, and 319 V/BK.
- Where is the master window switch grounded?
- Through circuit 57 BK to splice S500 and then to ground G204 (see grounds, page 10-11).
