I'd think you could just disconnect the old one and put the new one on by reversing the steps you performed to take the old one off. But - DISCONNECT THE BATTERY AND ANY SHORE POWER BEFORE YOU START! The solenoid is designed to transfer VERY high Amperage to the hydraulic motor and you do NOT want to get a jolt of that power while you are working!
