I too, have the five wire winch. When you take the cover off, you'll see two groups of wires. The group with three wires is the power grouping, the group with two wires is the ground grouping. If you'll notice, you should have a tiny wire that loops under the motor body, and connects at the ground post of the motor. That's the ground wire. It flows back into the solinoid box, straight to the plug in for the controller. It then goes up to the switch, and, when the switch is activated, goes back to the solinoids, splitting, and connecting with each and every one of the solinoids by way of one of the two little studs on each.
The power circuit gets power from the battery lead into the solinoid pack, goes thru the switch, and returns as a power in lead connecting with two solinoids, or as a power out lead connecting with the remaining two solinoids.
If the solinoids click. They work. It's EXTREMELY rare, for the internal contacts to go bad on a winch as new as yours (early models only have 3 wires to the switch, and are more common for this) Normally, when a solinoid dies, they don't 'click' anymore.
