It may not go to anything at all. I found this out after taking my dashboard apart and noticing extra harnesses. Harnesses are universal and not specific to the variety of models or options your Tahoe may or may not have.

Backside of the ac compressor. Hid by coolant hose. Had to go to salvage yard to figure this out in mine
