Review on 🔌 Wireless Winch Remote Control Kit - 23A DC 12V, 50FT; Universal Switch for Truck, ATV, SUV Winch; Includes Battery by Raden Maldonado

If you buy this remote control for a low power tipper trailer you will need to buy diodes (very cheap) and connect one each to the yellow and white wires. Connect the negative ends (tape side) of the diodes with a wire to activate the pump relay. Before the diodes (white and yellow wires) you need to make a connection to each of the solenoids for the valve to work. This allows you to activate the pump independently from up or down and at the same time open the valve up or down. The diodes prevent both solenoids from opening when the pump is turned on. You can find a video of this app on YouTube. It's easy and saves a ton of money on wireless remote controls! The only downside to these switches is a slight delay when releasing the button, so be aware of that.
