Assuming it is the same system as mine, the solenoids that control the jacks are already powered with 12 volts and are looking for a ground to operate. The different coloured wires coming down from the controller are simply grounds.
A jumper from the main solenoid battery feed to the smaller terminal going to the pump should operate the pump. A jumper from the coloured side of each pump solenoid to ground should make them click. You can move each jack from there. The retract solenoid is the same. If they all move then the controller is probably at fault.
On mine the controller was faulty and I made up my own switch panel. Hope that helps.
