The switch in the cab is setup to either open the trap or close it. I would like to only open the trap part way to empty the hopper slower. Can I do this by changing out the switch or do I need to put in a different solenoid on the trailer and switch in the cab? There is only 2 wires running to the solenoid. Any ideas would be apperciated!
