You have to run from the wheel to the pump. The ons for turning off the lamp and the pump are made on the sides and constantly work when moving and transporting in a case. And why do you need a flashlight with a short cord and a large distance from the wheel? In general, for the manufacture of 4, for the development of 2. I will redo it myself: A long wiring cord, 6-7 meters and a short hose, no more than a meter to the wheel.
