Power Door Lock & Door Ajar Switch Wiring Diagram - Latch Circuits P777/P292

This is a color wiring schematic for a vehicle's power door lock and door-ajar switch sensing circuits. A central module (fed FUSED B(+) at pin 1 of connector C3/C) connects to four door latch assemblies: driver (LATCH-DOOR-DRIVER), right rear, left rear, and passenger. The diagram identifies each circuit by number, gauge, and wire color: door lock relay control P777 18 LG/DB, passenger doors unlock relay control P292 18 VT/LG, front driver door unlock P910 18 TN/LG, and door ajar switch sense wires G75 18 VT (driver), G76 20 VT/YL (right rear), G77 20 VT/GY (left rear), and G74 18 VT/WT (passenger). Module connectors used include C3/C, C5/E, C6/F, and C7/G; in-line connectors I600, I650, I700, and I750 pass the circuits into each door, and splices SP777A and SP292A distribute the lock/unlock control lines. Ground circuits Z905, Z906, and Z909 (all 18 BK) run through splices SP1700, SP1702, SP1712, and SP1500 to ground points G105, G107, and G210. A red "OPEN PATH" annotation with an arrow marks a suspected break in the P777 door lock relay control bus near connector I600, apparently documenting a diagnosis of a non-working door lock circuit.
