Not connected to anything right now, no accessories on the truck besides the turbo. Everything on the truck works fine

Definitely some type of inverter. Doesn't appear to be 110v though.
Any numbers on it.

Maybe some kind of turbo shutdown timer? They used to be pretty popular to let the engine run for 3-5 min after you turn the key off to let the turbo cool down
