Driver's side, under the dashboard to the left of the steering column. No cover — directly accessible. Standard 16-pin OBD-II connector. Confirmed by multiple 2007-2014 Tahoe/Suburban forum posts ('right up under the dash just to the left of the steering wheel').
LHD (US market only): under the left side of the dash, below and just left of the steering column, facing down into the driver's footwell above the pedals. It sits in the lower-left dash area next to the body control module (BCM) connectors and the left instrument-panel fuse block, near the left footwell courtesy lamp where fitted. Same position on the Tahoe, Suburban 1500/2500, Yukon, Yukon XL, Denali and Avalanche, and on every trim across 2000-2006.
