How to Wire a 3500 lb Winch with Wireless Remote? | Wiring Steps

Wiring a 3,500 lb winch with a wireless remote requires connecting the receiver to the solenoid circuit and adding a ground jumper between the solenoid’s ground lug and its function terminal to activate the relay.

When you’re figuring out how to wire a 3,500 lb winch with a wireless remote, the process comes down to integrating the receiver into the solenoid circuit and adding one often-missed jumper wire. Without that jumper, the remote’s signal never reaches the relay, and the winch sits dead no matter how many times you press the button. The whole job takes about an hour with basic hand tools and a voltmeter.

What You Need Before You Start

The wireless remote kit replaces your winch’s manual rocker switch with a receiver module that talks to a handheld remote. The receiver uses four wires: red (12V power), black (ground), and two function wires (usually white/yellow or green/yellow) that signal the solenoid to spool in or out. You’ll also need a short jumper wire, wire cutters, crimpers, ring terminals, and a torque wrench. If you’re shopping for one, our tested roundup of the best 3,500 lb winches covers reliable options for ATVs and UTVs.

This installation works on any 12V DC vehicle with a permanent-magnet winch motor — typically ATVs and UTVs like the Honda Foreman 400/450 or Polaris Sportsman. The remote’s receiver is water-resistant but not waterproof, so mount it on a clean surface wiped with isopropyl alcohol.

Wiring a 3,500 lb Winch With a Wireless Remote: The Step Order That Works

The Champion Power Equipment manual and Tractor Supply’s installation PDF both follow the same sequence. Work through these steps in order, and you will not need to backtrack.

1. Disconnect the battery. Remove the negative terminal first to prevent any short while you work.
2. Cut the original connectors. Snip the connector on the original relay (manual switch) and the connector on the wireless receiver so you can splice directly.
3. Run the motor leads. Connect the yellow and blue cables from the winch motor to the contactor — yellow to yellow, blue to blue. Route the cables cleanly to the contactor box.
4. Connect the contactor power and ground. On the contactor, connect the red wire to the red 12V input and the black wire to the ground lug. Leave the nuts snug but not tight until all wires are in place.
5. Attach the rocker switch adapter. If your kit includes a rocker switch for backup manual control, connect it to the contactor — black to black, green to green.
6. Wire the remote receiver. Connect the receiver’s red wire to the center spade lug that carries constant 12V. Connect the black wire to the ground lug (shared with the solenoid ground). Connect the green/yellow and white/yellow wires to the solenoid’s OUT and IN terminals — order matters here, so note which is which.
7. Install the critical ground jumper. Run a jumper wire from the solenoid’s ground lug to the small lug located between the IN and OUT function terminals. This is the step nearly every first-timer misses, and without it the solenoid relay will not engage.
8. Torque and secure. Install the rubber terminal boots and secure all loose wires with cable ties.
9. Reconnect the battery and test. Press and hold the POWER button on the remote for three seconds — the red indicator light confirms the wireless system is active. Test spool in and out before loading the winch.

What Is the Critical Ground Jumper?

The ground jumper is a short wire that connects the solenoid’s ground lug to the small function terminal lug between the IN and OUT inputs. The wireless receiver module sends a low-current signal to tell the solenoid which direction to spin the motor, but the receiver alone cannot complete the ground path that actually energizes the solenoid relay. The jumper provides that path. Without it, pressing the remote button does nothing — the receiver lights up, the solenoid clicks faintly, but the winch stays still. The Champion Power Equipment installation manual shows this jumper in the wiring diagram, and every successful field install depends on it.

Common Wiring Mistakes to Avoid

Four errors account for nearly every failed wireless remote install on a 3,500 lb winch. Skip them and you will save yourself a rewire.

• Missing ground jumper. Already covered — the most frequent cause of a non-functioning remote. Add the jumper before testing anything else.
• Cutting the antenna wire. The blue wire on most receiver modules is the antenna, not a function wire. Cutting it kills the remote range. Leave the blue wire intact and route it away from metal surfaces.
• Reversing the function wires. If the winch spools in when you press OUT and vice versa, swap the two function wires on the solenoid terminals. No damage done, just a quick swap.
• Over-tightening the contactor nuts. The contactor terminals are softer than motor terminals. Exceeding 4.5 N·m (40 lb-in) can crack the plastic housing or strip the threads. Use a torque wrench set to that value.

Torque Values That Prevent Damage

The two torque values in this install are not negotiable. — tight enough to hold under vibration but not so tight that they strip the stud. — the plastic housing cracks easily if you overdo it. A beam-style torque wrench that reads in lb-in is the right tool; a standard socket wrench by feel is how terminals get broken.

Final Wiring Checklist

Run through this list before you spool out the rope on a real recovery:

• Battery disconnected during install, reconnected only after all wires are secured
• Ground jumper installed between solenoid ground lug and function terminal lug
• Blue antenna wire intact and routed away from metal
• Function wires correct — test spool direction before loading
• Terminal boots installed over all contactor connections
• Cable ties securing loose wire runs away from moving parts and heat sources
• Remote POWER button held 3 seconds to transfer control — red indicator on
• Stand clear of the tow path when testing, never switch direction while motor is running
