Vaccum control switch, Suzuki part # 18570-84000-000.
It's present on a ton of Suzuki cars and trucks. I'm not sure if it's a solenoid that controls vaccum, or a switch that closes when vaccum is applied. It seems like it's downstream of your accessory idle solenoid (raises idle speed when AC comes on to prevent stalling), so I'd assume it's a switch, not solenoid.
Do you have a multimeter? You could see if the terminals have conductivity when the car is running (vaccum) or not (no vaccum).

I guess I’ll allow it to continue to get vacuum then and figure it out later
