Module explanation

[TeaSpoon]

Hey everyone,
I have a new to me 1st Gen Denali (2000) that shares most everything with the 96-99 but the front clip. I’m trying to figure out what everything goes to, and I have this circuit board in a grey plastic box that sits under the dash next to the emergency brake that I’m trying to figure out what it goes to. It’s an 8 pin connector. Thanks for the help!

Does it have a part number on it?

I took it apart today and pulled the board out which had a number on it. Google says it’s for daytime running lamps. I know the drl has a vented module also, didn’t know it had a board. When I pulled the board, the headlights and fog lights don’t work. I’m trying to narrow down the interior lamp switch, but it looks like this model has it built into the bcm unfortunately.
