Video Transcript for Superwinch Electric Winch Wiring Kit Installation - 2004 Ford F-250

All right, today in this 2004 Ford F250 were going to install part number SW2008 from Superwinch. This is our wire harness for the back of the truck. Well go ahead and mark the ends of our cable. Well go ahead and pair the end with the gray connector to see which is positive and negative and well go ahead and mark the ends. Well go ahead and take our two 5-ft long wires with the gray connector and well route those from the front of the vehicle to the battery. Weve got one wire in and well go ahead and repeat the same process with the other wire.

All right, now well go ahead and attach our positive wire to the positive turn on our battery. Then well go ahead and attach the negative wire to the negative poles on the battery. Next, well go ahead and route the 19-ft long wire thats supplied. Youll have gray end with one long wire and one short wire. The long wire will run up through the frame and up to the battery in the positive side.

The short wire will run along the edge of the frame and attach to the frame at the back of the truck for ground.First off, well go ahead and put our gray connector up where we want it and then well zip tie it in place. Then well continue on running our wire from the front and well make sure we stay away from anything moving like suspension components or anything hot like the exhaust. In this case, we ran along the frame on the inside using zip ties with some existing holes in the frame to hold everything in place. Theyre rounded up into the front of the vehicle and underneath and up towards the battery. When we get to the battery well go ahead and loosen up the nut on our terminal and go ahead and install it.

Then we can go ahead and tighten it back down.Well stop right here and install our ground wire. Were going to install it to the cross member located here behind the spare tire. Well use number 14 self tapping screw to attach it to the frame. Now we can go ahead and add our cover to the plug and were good to go for installation on the truck.Now this kit does come with extra set of cables for quick attachment for your winch. The part number were working with is SW1698201.

Well start off by marking our wires positive and negative. Now theyre marked at the connector and well go ahead and follow them back and put a mark on the end. All right, to install our wiring for a quick connect, now well go ahead and undo the cover on the winch and well remove the positive wire first, that will be the red one. Then well install our positive cable going inside. Well just go ahead and reassemble it. Next, well go to the bottom of the winch and install the ground wire. We have some bolts on the bottom. Once again, well go ahead and remove the original one which will be a black wire and then install the new cable. Well unbolt it and bolt the new one in place.Now well go ahead and show the two connectors working together. Well simply push them together and our winch is connected and are ready for service. With that, that finishes our installation of all these components for part number SW2008 from Superwinch on our 2004 Ford F250.

- SW2008

by: charles l.03/25/2011

The product was exactly as expected; my rating is a 5 Excellent, if it shows a 4 it is because there were 2 selections below Poor and I didn't want to guess that the bottom circle was Excellent, in case it wasn't. I run a Warn M8000 12V winch, and this connection and set-up work perfectly for it. Installation is a breeze, just make sure you keep the wiring clear from the exhaust system, of course this goes with any electrical wiring, regardless. Also, the price, service and delivery were Great as well, Thanks to I can definitely recommend this product, and 10380

Do you have a question about this Accessories and Part?

  • Correct Way To Wire Warn Trailer Winch Up to Be Powered By Truck Battery
  • Yes, I can guide you through the correct way to power your Warn 4000 lb winch by your vehicles battery. You will need to use the item you selected, Trailer and Vehicle Electric Winch Wiring Kit, part # sw2008, which uses quick disconnects. You can use the Tow Ready Battery Isolation Solenoid, part # TR118665, in-line with the positive battery cable to keep from draining power from the vehicle battery. Hooking up the winch with part # TR118665, would only allow the winch to be used when...

  • Using 7-Way Trailer Connector 12-volt Accessory Circuit to Power Boat Winch
  • An electric winch used to pull a boat up on a trailer is designed to be wired directly to a 12-volt battery. The wire that feeds your 7-way trailer connector is too small in gauge to be able to handle the amperage draw of a winch. Attempting to use the 7-way to power the winch will almost certainly lead to blown fuses. Typically, a winch would be connected to an auxiliary battery located on the trailer. The auxiliary battery can be maintained with the 12-volt circuit from the 7-way,...

  • Providing Power to Trailer Mounted Winch from 7-Way Trailer Connector
  • The wiring that feeds the 12-volt accessory circuit on the 7-way trailer connector is of insufficient gauge to allow enough power to pass through to run a trailer mounted winch. The main function of that circuit would be for lighter-duty applications, such as providing power for interior trailer lights or to maintain a trailer mounted battery. To provide power for your trailer mounted winch, you can either install a battery on the trailer to power it, or use a quick disconnect like...

  • Wiring for Electric Winch at the Front and Rear of a 2015 Chevy Silverado 3500 Duramax
  • First, you are going to need a couple sets of quick disconnects such as # SW2236. You will need enough 2 to 4 gauge wire to reach from the front of the truck to the batteries and from the rear of the truck to the batteries. We do not currently have wire that large. But another option is to get a couple of winch wiring kits, # SW2008. The winch power and ground wires will attach to one disconnect and the wiring to the batteries will attach to the mating quick disconnect. Diesel trucks...

  • Can a Trailer Connector be Used to Power an Electric Trailer Winch
  • Electric winches should have a direct connection to a battery for power. The wiring in a trailer connector, like a 7-Way, and an adapter like # HM47675, is not a heavy enough gauge to effectively power a winch. Also, the farther away from the power source the winch is, the heavier the wiring will need to be. I recommend using a wiring kit specifically for electric winches like Trailer and Vehicle Electric Winch Wiring Kit, for up to 16.5K Winches, # SW2008. I have included a link to...

  • Can 7-Way Trailer Connector Accessory Circuit be Used to Power Trailer-Mounted Winch
  • The 12-volt accessory circuit lacks the amperage to power a trailer mounted winch. Your best bet would be to either install a 12-volt deep cycle battery on the trailer, and use the 12-volt accessory circuit to keep that battery maintained, or use a winch wiring kit like part # SW2008 and connect the winch to the vehicle battery. If you use the 12-volt accessory circuit to maintain the trailer-mounted battery, I would recommend installing a battery isolator, like part # TR118665. The...

  • How to Charge, Maintain and Wire a Winch Battery, Wiring Front of Truck to Trailer
  • Running a charge line from a vehicle charging system for charging a trailer mounted battery can be accomplished but the vehicle charging system does not have enough power to charge a battery that distance away from a discharged state. The charge line is only capable of maintaining a sufficiently charged battery while the vehicle is running. In your case you have two options. The easiest is to use a battery charger like the CTEK MULTI US 3300 12-Volt Universal Battery Charger w/ Pulse...

  • How To Maintain Trailer-Mounted Winch Battery Using 12-Volt Accessory Feed
  • First, on the towing vehicle, you will need to install a battery isolator, # TR118665. The flow of current will go from the vehicle battery to the isolator. From the isolator it will go along a length of 12 gauge wire, # 12-1-1, to the vehicle side trailer connector via a 30 amp circuit breaker. Next, 12 gauge wire will need to run from the trailer side 7-Way to the positive Trailer battery terminal. If the winch came with a circuit breaker it will need to go between the winch and positive...

  • Quick Connects for Power a Trailer Winch from a Vehicle Battery
  • There are some quick connect options for winches. We have # SW2236 for 2 to 4 gauge wire, # SW1551 for 6 to 10 gauge wire. We also have # DL24085 for 6 to 16 gauge wire and # DL24086 that accepts up to 10 gauge wire. I have included a link to our FAQ article on wiring an electric winch that should be helpful.

  • Need An Electric Winch To Pull Vehicles Up On A 22 Foot Car Hauler
  • The SuperWinch LT2000 Electric Utility Winch, part # 1220210, you have referenced will only have a rated line pull of 2,000 lbs. The rated line pull of 2,000 lbs. will pull a rolling load of 10,050 lbs. up a 6 degree incline, but as the incline increases, the rolling load capacity will decrease. Also, those loads are based on the just one layer of wire wrapped around the drum. Each additional layer of wire (when the winch wire is laid on top of itself) reduces the winchs pulling capacity...

  • Recommend An Electric Trailer Winch To Winch Full-Size Truck Onto Trailer
  • To determine which electric winch you will need, you need to find out the weight of your full size pickup truck. The item you selected, Superwinch LT2000 Electric Utility Winch, part # 1220210 has a capacity of 2,000 pounds. I would recommend the Superwinch S5000 High Performance Utility Winch, part # 1450200 which has a 5,000 pound capacity. This winch should have more than enough weight capacity to winch your full size pickup truck, but you will want to double check to make sure the...

  • Winch Wiring Diagram for a Ford F-250 with 2 Batteries Under the Hood
  • The batteries under the hood of your F-250 should be wired in parallel, providing 12 volt output for additional power and starting ability. If your batteries are wired in series for 24 volt output, you will need to add an additional 12 volt battery to operate the winch. Wiring a winch with the Superwinch Wiring Kit, # SW2008, is accomplished by running the 25 foot long 2 gauge wire with connector from the positive post on one of the batteries to the back of the vehicle and mounting it...

  • Electric Winch Recommendation for Loading Classic Cars On an Enclosed Car Trailer
  • When using an electric winch to pull a rolling load on to a trailer, it is typically recommended that the winch have at least the capacity of the weight of the vehicle. The Superwinch Husky 8 Heavy Duty Recovery Winch, # 2401A, that you referenced may be excessive for your application. This winch was designed for vehicle recovery and often times the load is not rolling. The rolling load capacity of a winch is typically greater than the rated line pull and the rolling load capacity increases...

  • Wiring Options for an Electric Winch Powered by an Additional Battery
  • The easiest way to wire the battery for your winch will be to use the 7 way connector on your vehicle if you have one on your 2006 GMC Truck. You can get a 7 way trailer connector like part # A7WCB and use the Jacketed 2 Wire, part # 10-2-1, to connect a wire for the power and a wire for the ground in the connector. You will then run the ground wire, or white wire, to the negative terminal on the secondary battery and run the power lead, black wire, to the positive terminal on the battery....

  • How to Install the Wagan 1000 Watt Power Inverter # 02294
  • The Wagan Power Inverter, # 02294, comes with two 6-gauge wires with ring terminals and alligator clamps. They are only a few feet long. This inverter can be hard wired and the proper gauge will depend on how long you plan to run the wires. For example, if you will be running the wires 8 ft round trip, then you will want to use 6 gauge wire. If you will need 9 - 10 ft of wire, then you will need to use 4 gauge wire. If the cables will be running 11 -21 ft round trip, then you will want...

  • If you are wanting to put a larger deep cell battery in your trailer to power your winch and recharge it from the battery on the 2008 Dodge Ram 2500 you will need to wire it directly with the Superwinch Trailer Wiring Kit, # SW1520, depending on what size winch you are using. This kit is designed for up to 4,000 lbs. winches. The Superwinch Trailer Wiring Kit, # SW1520, has 19 feet of 6 gauge double wire to run from the rear of the vehicle to the front.

  • Is it Necessary To Ground a Trailer Mounted Auxiliary Battery To Trailer Frame
  • The way you currently have the system set up will work just fine for you. However, if you want to use the 12-volt accessory feed from your 7-way to maintain (not charge) the trailer mounted winch battery, the battery would indeed need to be grounded to the trailer frame. This is a very commonly found set-up, you would not need to worry about any problems between the vehicle and trailer battery. If the accessory circuit is used to maintain the battery, I would recommend installing...

  • Possible Quick Connect Recommendation for a 12k Badlands Winch
  • While it most likely would work, the Trailer and Vehicle Electric Winch Wiring Kit # SW2008 has never been tested on your Badlands 12,000 winch so I could not say with 100 percent certainty if it would work for you. If your winch can be powered with 2 AWG wire then most likely this kit would be adequate for your winch as this winch is confirmed to work on Superwinch winches up to 16.5k in capacity.

  • Portable DC powered 12 Volt Vehicle Winch Recommendation for a 1999 Toyota RAV4
  • There are several things to consider when choosing a winch. If you are looking at having to potentially use the winch to retrieve the 1999 Toyota RAV4 then you need to consider the incline, terrain, angle, and total load. For example a winch rated for 2,000 pounds pulling a rolling load on level ground can pull much more than that 2,000 pounds. On a 10 percent slope for example it can pull 10,050 pounds. But a steeper incline will reduce the capacity. If you foresee yourself in all sorts...
