System architecture map
The table of contents is organized by major assemblies (powertrain, chassis, braking, restraints, body/HVAC) plus an electrical backbone section with wiring-harness, fuse/circuit-breaker, charging/starting, and diagram-focused indexing—useful when matching components and circuits across H3 and H3T configurations.
Configuration signals to match
If your vehicle identification aligns with the H3 vs. H3T split and one of the listed engine codes (L52 / LLR / LH8), this manual’s scope is structured for consistent cross-checking across mechanical systems and electrical architecture without blending unrelated model families.
