Trailer mover rewire

Hello,

I have an iDrive TDS-1001e. It has 3 motors, motor controller with wireless control and runs of a 12v battery. This system is permanent fixture for a trailer and designed to move it around easily once off the vehicle. There is one motor on each wheel for turning, forward and backwards movement. I would like to make this as simple as possible but I would still like the option of wireless control. How would I wire for direct control? If I need a board, which board do I need for direct control or wireless control?

Can you provide a few additional details about the setup? It seems the system already has wireless control, so you would be looking to physically add wires? You might want to contact the manufacturer to see if they have options, because otherwise you would be hacking the system.
