B+ wire connection for Renogy DC-DC Charger

Hey fam! I had a quick question about installing my Renogy 40a DC-DC charger.

I have a 2012 Chevy Express Box Truck. My question is where to connect the B+ cable from the battery charger? I know it needs to connect to something that only has current when the engine is running.
Does anyone have any advise on where to look in this type of vehicle specifically? Is there a bus block or something that anyone is familiar with?

Thank you so much!

I normally just go to the fuse box, and pick something that only comes on with the ignition switch. It varies per vehicle.
