I'm new to food plots. I'm getting setup to build a couple of food plots next year (clover). I bought a used 2000-2003 (Unsure of year) Plotmaster very cheap that was used very little, but they lost the controls for the for the electic lift system. Can anyone tell me what the four wires do? (up, down, power, and neg). I don't want to buy a new controls. I plan on putting the food plots on soft old road beds.

Thanks
Jeff
