The starter relay is stuck closed. Working properly, that provides power to the solenoid to engage the flywheel and turn the starter when you engage the key to the START position. Power should disconnect when you turn the key out of "START" but it's not going to remove the power if the relay is seized closed.
From the starter, run the POS wire back to the engine bay... that wire will be connected to the starter relay. Tap on that a bit and it may temporarily work correctly again, or disconnect the wires from it completely. With the wires disconnected, try to start... nothing should happen. Then touch the wires together and the van should attempt to start. The starter circuit is disengaged in reverse due to the neutral safety switch, which makes sense.
EDIT: I had the same issue once. I recommend getting one of these for your battery to allow you to quickly and easily disconnect the power when needed: https://www.amazon.com/Ampper-Battery-Disconnect-Isolator-Vehicles/dp/B07JZ9NDH2/ It's just a good little $15 upgrade addon.
