There are a couple ways to identify which wire is the power and ground wire on your Dutton-Lainson StrongArm Electric Winch # DL25500 (SA5000DC). You can follow the wires coming out of the winch, the ground is a shorter wire that will be routed to the frame. The power wire is a longer wire that will be run up to the battery.

You could also use a circuit tester # PTW2993 to test for which wire has power.
