Install it properly
First choose an installation site accessible to you. Align an unobstructed path to the car that you are loading. Prevent any metal-to-metal contact with the wire rope. Mount the winch close enough to the trailer’s front to pull the vehicle completely on. If it’s mounted under something, such as a toolbox, leave enough space to access the winch.
Consider a pulley block
With a hook for mounting and a pulley for the wire rope, a pulley block lets you offset the  winch but retain a straight shot. A pulley block can also be used to nearly double the winch’s capacity by simply attaching the pulley block’s hook directly to the load and the winch’s hook to a sturdy mount near the winch.
Wire it right
A trailer wiring kit, like the kind available from Superwinch, makes it easy to get power for the winch from the tow vehicle’s battery.
To maintain electrical performance from the battery to the winch, we recommend dropping 3 wire sizes for every doubling of the length of the standard wire harness. Example: No. 6 to No. 3 or 2 gauge. A quick disconnect plug for the truck comes prewired with a negative lead. Simply install the special terminal to the positive side of the quick disconnect and position the plug at the rear of the truck, perhaps under the bumper.
If your tow vehicle isn’t equipped with a towing package that includes a dual-wire ground setup, Superwinch recommends installing the negative battery terminal strap provided with their winches. Take care that your wiring has fully secured leads which are clear of hot or moving parts.
Accessorize For Safety
Maximizing winch safety and performance is as simple as attaching the proper accessories. Superwinch offers roller fairleads, recovery straps, gloves, and many more accessories designed for your special needs.
* RLP - The weight the winch could pull perpendicular to the ground with a single line on the first layer of wire rope on the drum.

•Winches are not intended as a load securing device.
All ratings are based on the first layer of wire rope on the drum. You could experience a loss of up to 13% pulling capacity per layer of wire rope (see example below).

Many of our units come standard with 50' of wire rope or more. In some cases this may be a disadvantage. Due to the length of your trailer you may be starting on the 3rd or 4th wrap. Simply shorten the wire rope to your needs. If you can work with 30', then shorten the wire rope and your performance will improve.
NOTE: To maintain electrical performance from the battery to the winch, we recommend dropping 3 wire sizes for every doubling of the length of the standard wire harness.
Choose the right winch, use the right accessories and follow all the safety guidelines. Your winch is a powerful machine and whether you use it for serious recreation or serious work, remember that pulling a very heavy load is a dangerous operation.
Never use a winch to move or lift people. Never use a winch as a (vertical) hoist or to suspend a load.
