Component-location diagram showing the liftgate lock relay and harness routing at the passenger B-pillar with a numbered legend.

AI caption · Photo 15 of 15

This document is a single-page component location diagram titled "Liftgate Lock Relay." It shows an interior line drawing of a vehicle's rear cargo area, focusing on the passenger-side pillar region. Two numbered callouts identify the components: item 1 is the liftgate lock relay, shown mounted on a bracket with an attached wiring harness routed down the pillar and along the cargo floor; item 2 identifies the passenger B-pillar, the structural location where the relay is installed. A directional arrow in the illustration indicates vehicle orientation. The document was uploaded to a 2004 Chevrolet Tahoe gallery and is part of an album containing related electrical/body diagrams (front door switch, HVAC module, interior light schematic, rear window, and rear wiper diagrams). The page itself contains no year, make, model, part numbers, wire colors, or torque specifications — it serves purely to show where the liftgate lock relay is physically located, which is useful for anyone diagnosing liftgate lock actuator or relay problems and needing to find and access the relay behind interior trim at the passenger B-pillar.
