Another electrical question

[jaredpears]

I’m new to the square body scene so I don’t know what a lot about these trucks so I’ll probably be posting a lot. Anyways, as I dig farther into the repairs on my new suburban, I have 2 connectors next to the ashtray, I know the top one is for the back window, which I need to get a new switch for. But I don’t know what the bottom one is for and I can’t find a good picture of the dash with both of those

Rear heat possibly. I just took a suburban apart and if I remember the top was window and the lower one was rear heater fan.
