Note: The following wireless installation instructions are designed specifically for the universal wireless winch remote kit by ProMark Offroad.
For normal winch recovery loads and conditions, your existing electrical system is adequate for the wireless upgrade. For heavy winching, consider upgrading your electrical system.
In order for the recovery winch to work at its full potential, a fully charged battery and proper connections are essential. Keep the vehicle’s engine running during the winching process to keep the battery charged.
To install your wireless winch remote, carefully follow the instructions and diagrams below for routing the electrical connections:
Test the setup for correct operation before using your winch on the trail or in a recovery operation. If the remote control does not operate correctly, check all wiring to ensure that connections are correct and secure. Also, check the remote battery and replace if necessary (23A battery).
For best results with your new wireless winch remote, take note of the following recommendations:

Do not route electrical wiring over sharp edges or in places where they will touch parts that become hot. If the wiring is allowed to chafe or melt, this could damage the insulation that protects the wiring and cause a short circuit. Ensure that the wiring harness does not interfere or come in contact with any hot or moving engine, suspension, steering, braking, or exhaust parts.
Avoid routing the wiring through or near moving parts. In the case of wiring a handlebar thumbswitch on an ATV, make sure there is enough room to fully turn the handlebars without stretching the wiring. Then cable tie the wiring to hard points on the handlebars and bike to secure it in place. Secure the switch and wiring to the handlebar with black electrical tape to prevent rotation.
Insulate and protect all exposed wiring. Use insulating terminal boots as needed to prevent shorting and reduce the risk of electrical hazards.
When attaching wires to the winch motor or solenoid terminals, hold the inner nut with a wrench while tightening the outer nut with a second wrench. Do not allow the terminals to rotate in their housings. Rotation could cause internal wire damage or part misalignment.Install all electrical wiring only after the winch is mounted on the vehicle. Do not attempt to install wiring when the battery is connected. After installing and securing all wiring, take a minute to ensure that your system is properly installed and free from restrictions. Then you may attach the wires to the positive and negative terminals of the battery.
Make sure that your battery or power supply meets the minimum requirements for the operation of your winch. A 12 volt DC battery is required for most electric winches. Even with sufficient battery power, you will need to make sure not to overload or overheat the winch. Electric winches are designed for intermittent use. For long pulls, stop winching periodically and allow the motor to cool before resuming operation. If the winch is under heavy use, we suggest installing an auxiliary battery and heavy-duty alternator to handle the load.
If you can’t get at your recovery winch when you need to use it, or if you have to take apart the entire front bumper just to change out the cable or work on your winch, it’s going to be a pain to maintain your winch. On the other hand, mounting the winch behind the front bumper means that it’s more difficult to steal. So figure out what’s most important to you, and choose your mount location accordingly.
Another thing to consider is whether or not the winch mounting location allows you to keep the factory bumper. If you plan to upgrade the bumper anyways, no problem. But if you want to keep the factory bumper, you’ll need to take that into consideration when you choose a mounting location.The lower the winch, the less it blocks airflow to the radiator. Depending on what type of offroading you do, a low-mounted winch or a winch mounted behind the factory bumper may be just fine if you play it safe on the trail and wheel in dry conditions. On the other hand, if you wheel in a lot of mud, snow, or water, you’ll want to mount the winch higher off the ground in such a way that your setup doesn’t limit the approach angle of the vehicle.
Another option you have is to get a receiver-style winch mount that allows you to mount the winch when you need it and take it off when you don’t.

Winching Tip of the Week: Make sure your battery and alternator are up to the challenge of winching.
Electrical winches use a lot of power. Make sure your battery and power supply meet the electrical requirements for your winch model. Check the specifications for your winch supplied by the manufacturer to make sure your battery and power supply are able to handle the electrical load, or you could risk damaging your winch, battery, or alternator.
If the winch is under heavy use, consider upgrading to dual batteries and a heavy-duty alternator for best performance.
The winch contactor location may affect how long the contactor will last. Despite the fact that the contactor is sealed, we still recommend that the contactor be located in a clean, dry area to protect it from exposure to rain, water, and other elements that wear down the protective seal prematurely. Repeatedly submerging the contactor in water may compromise the waterproof seal. The more you can keep the contactor out of the water, the better.
The contactor should also be mounted close to the battery, if possible. The closer the contactor is to the source of power, the better. Also, the length and gauge of the wires supplied with the winch are designed to safely carry a certain amount of electrical load. If you swap out these wires for longer wires, make sure the new wires can handle the load.
If the wires are not long enough to reach the battery, switch mounting point, and winch, you may need to increase the length and/or wire gauge of the wiring. If you choose to locate the winch or switch at a greater distance than the wires permit, it may also be necessary to purchase a heavier gauge wire to get the best performance from your winch. If the total length of the additional wire to be added exceeds 10 feet, use a heavier wire gauge.
Typical locations for mounting the winch contactor include in or near the rear storage box and, on some models, under the seat. Other locations include under the front hood, in or near the battery compartment, and inside the tool box. The location options will vary depending on the make and model of your ATV. Make sure the location you choose allows sufficient clearance from all metal components, such as frame tubes.
Once you choose a location, drill mounting holes, but do not install the contactor yet, as it is easier to wire the contactor before mounting. Disconnect the vehicle ground and positive leads from the battery before connecting the wiring. Secure the wiring to hard points on the vehicle with cable ties and/or electrical tape. Make sure the wiring is not pinched (for example, by the seat) or pulled (such as when the handle bars are turned). Also make sure that the wiring does not interfere or come in contact with the engine, suspension, steering, braking, exhaust, or any sharp edges or moving parts.
Always choose a mounting location that is strong enough to withstand the load you will be pulling with the electric winch. Installing the winch on an insufficient structural support may cause major damage to the vehicle and winch.
Install the winch with the proper orientation as stated by the manufacturer for your vehicle model. Installing a winch or part of the winch backwards, upside down, or in any other incorrect way will cause the winch to operate incorrectly or not operate at all. Mount the winch before connecting the wiring.
The winch cable must spool onto the drum in the underwound position. The winch is designed to spool in and out in one direction only. Reversing the direction of the cable as it spools onto the drum may damage the winch. If your winch is equipped with an automatic brake, the underwound position is required for the brake to work correctly.
Spool the winch cable onto the drum with adequate tension on the cable. A tightly wound cable is less likely to work its way down into the inner layers of rope. Without any tension, the cable will spool loosely and can easily tangle or be damaged.
