Solenoids are the only protection system of electromagnetic switches that stand in between the power source and the winch battery.
These vehicle-mounted boxes ensure the safe passage of power to the winch motor, ensuring no damage to either the switch or battery.
Solenoids can be used either as a pair, one as reverse and the other as forward or as a combination of 4, two for reverse and two for forward.
The two Solenoid configuration is typical of permanent magnet winches while the four Solenoid configuration is found in Series wound winches.
Wiring the Solenoid box
Most Solenoids are built with the same principle.
However, brand-to-brand instructions for wiring the Solenoid come with the Instruction manual with the Winch.
Here is a brief guide to wiring up the solenoid. It may not be an exact procedure for the winch you may have, but it does come close.
The wiring from the winch to the solenoid and the battery to the winch requires a great deal of care. Avoid touching any rusted metal or sharp edges with the wires.
The majority of people are unaware that wires that are smooth and metal can become entangled with dirt or mud, so this should be taken more seriously.

The cables must also be connected to the winch. The winches have color-coded lugs on purpose to minimize the risk of mistakes, the cables lug onto the winch solenoids, and the cables must not be tightened too tightly. The solenoid may become damaged if too much torque is put on the cables.
These basic connections apply to every Solenoid. Figuring out which wire connects where may take some time, but all you have to do is follow the instructions that come with the Manual.
