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

On this 2004 Ford F-250 super duty, we're going to review and install the bulldog wiring kit, part number BDW20207. First of, all hand cover the parts that come with this part number. This is our main wire harness right here, which is constructive of two gauge material and its overall length, is going to be 24 foot long. We'll take a look at the ends. First of, for your typical assessor, which should be the winch that goes on here. This is going to be ride towards the back of a truck. Comes with a cap, to cover up when it's not being used.

Also there's a little lanyard, so don't lose it, you can attach it to somewhere on the vehicle. On the other end of our wires, these is ground one. It's got all seal that ends on it. Our negative wire, here, it's intended to be installed on the negative side of the battery. Here's our red one that goes to the positive side of the battery and the same style construction. For your accessory or plug into it, comes with it's own plug and some logs to get crypt on to two gauge wire as well. This also comes from some heavy zip ties, to help it secure it to the vehicle.

To start off our install, I'm going to take this end of our wire harness and I'll route down behind battery, down towards the frame. I'm going to go through this opening right through here. We should be close to the inaudible 00:01:20 liner when guided from there, once we get down to that point. Once we have it through our opening, we'll go ahead and pull all the slack through and make one ground connection to our battery. We'll go ahead and make a connection to the negative side of the battery. We'll go ahead and loosen up the nut here, and we'll go right ahead and remove it.

Right, what I'm taking a wire and add it to our negative side of our battery. Now of course this is going to be a bit of sloppy fit, so I'm going to use the number ten washer on my bolt, to help give it some grip on the cable when we reinstall the nut. Now, I like to leave my positives, terminal as one of the last things I connect up. Let's leave this alone for now, we'll go back underneath the truck and route our wire to the back. Now we'll run a wire back, we'll make sure we stay away from anything moving like suspension components or anything hot like the exhaust. We'll go ahead and run ours long the frame as best we can and out towards the bumper. Now we'll go ahead and show you how we routed our wires.

Basically, we tried to follow the top of the frame rail as this is possible. Around this body mount right here, where it will rest on the frame, go along through here. We used some zip ties that came with the kit, to help hold it in place. We've basically used the existing holes in the frame and went along the side of it. We got over by the axle a bit, we had to run over the top of the frame and then start running inside the frame and let the cross numbers hold the wire up for us. Now you know, so we have some extra wire. We place some simple loops in there, zip tie it together and by this time we we're out of large zip ties, so we went back to some small zip ties. Held everything up against the inside edge of the bumper. There we have a wire harness right here. Now our kit does not come with a bracket or anything to hold in place, so, you could leave it like this, where the cover will be fine or, you can advocate your own bracket for it. If you choose to mount up to a bracket, or something from this vehicle, it does have holes built in for that purpose as well. Now we'll install our cap, we're in between the two wires and back over itself this way. That way your cap always stays with it. If we're wiring around, we'll go ahead and move to the front of the truck and hook up a positive cable. We'll use this pre-existing stud right here. We'll go ahead and remove the nut, using a ten millimeter socket. With this time, instead of using the extra washer on here, we just used to use a smaller ring of familiar wires stacked on top and let that do the work for us. Then we'll clump it down when we re-install the nut. This goes to the back of the truck one more time and we'll go ahead and use the tester to verify if we have power going back. We use our tester on it, even labelled negative, so we'll put our ground clamp there and we'll check the other side. Now you have power going back to it and inaudible 00:05:03 ad on our own accessory. Now we've verified power's going through our cable. I think we're good to go. L-Fisher for part number BDW20207. The bulldog wiring kit, on this 2004 Ford F-250 super duty.

Bulldog Winch Rear Wiring Kit - Quick Connect to Terminal End - 2 Gauge - 24' Long - BDW20207

Average Customer Rating:  4.9 out of 5 stars   (19 Customer Reviews)


This works real well for charging cables, truck hitch mounted winch and recharging batteries on camper and dump trailers.


Only good way to power my trailer winch-far superior to a separate battery



Great-5-no problems since going on truck battery’s power


Install from rear to front and its done


After a temporary "fubar" with my order, it finally arrived. I couldn't be happier with the quality & design of this kit. VERY well built. And the installation video was perfect for a DIY'r like me. Thank U etrailer. U guys really came through!!!

Michael K.


AWESOME !!! Saved my butt 2x’s all ready. 2 days stuck in mud, digging, cudn’t reach winch w front mount. Pulled winch cradle off ft bumper. Moved to rear mounted Bulldog plug & receiver. Drug my big Dodge Ram up & out. Wud NEVER have worked wo that double Bulldog winch plug setup. THANK U!!!


Great product, worked perfectly. I installed a winch on my car hauler trailer with a tip up bed. The 24' wiring kit was the perfect length. I have a 4 door/ long bed truck and with the trailer bed tipped up the extra length was perfect to connect to the winch. The plug for the winch side was easily soldered onto my winch leads. Very happy with the product all around.


Just what I needed. Now I can charge the batteries on my trailer as I travel and don't have to rely on solar alone.
Good quality product and shipping.





Hi quality product, better than I expected. Also reasonably priced. It will be a quality accessory added to the vehicle and be interchangeable to the next vehicle I purchase. Thanks etrailer for making my shopping easier. AND Talk about quick service and delivery all 5 Star for me. I purchased both front and rear hook ups for my winch or other things that will need power and they are both just what the doctor ordered.

Came in 2 days after I ordered it! Have this to complement my bulldog front connection. Heavy duty 2 gauge wire and connections are made well! Pleased so far.


Best service! And prices also. Never going back to amazon if I can buy it from etrailer.



GREAT! I plug this in daily and it charges my trailer way faster than the 7-way power plug. I had it installed by a local shop. THANKS!


pexcellent! Ran front to back 3500 hd crew cab without difficulty..,Powers wench on trailer great!


Product arrived on time as promised and I am very pleased with the quality of the materials used. I look forward to installing it this weekend. Thanks etrailer.


All products received in good condition and have performed as expected.


Very well built and works great. I did notice the price dropped $71.00 between the time I ordered it to the time it was received. Hopefully I can get that credited back to me.


Just what I needed and fast service!


Great product and even better service.


Product should work great.

  • Wiring Needed to Power Dump Trailer Directly From Truck Battery
    It sounds to me like you are wanting to power the dump trailer directly from your trucks battery. If this is the case you will want to start by making sure that the power draw for the lift would not overload the truck. If all looks good, you could use part # BDW20207 which is typically used to wire electric winches but would also work for this type of set-up. The trailer and vehicle wiring kit includes 24 feet of 2 gauge double wire with quick connections. I've attached a video to assist. If...

  • Can 12k Winch Ground to Frame or Does it have to Run to Battery Post
    This is a really great question that we debated here not that long ago actually. A lot of people have done it both ways and it seems to be fine for most people to ground through the frame. But on higher drawing winches like what you have it's best to run the wire (I know it's expensive) back to the negative post of the battery. One way to get a good idea if you can go to the frame is to compare the thickness of the winch's ground wire and the thickness of the ground strap ran from your...

  • Preferred Trailer Winch Wiring Ground Location
    You are correct that grounding the wiring for a trailer winch like the Bulldog Winch Rear Wiring Kit # BDW20207 does not need to be run all the way to the battery in order to ground but it is often the most secure. Running the ground the entire length of the vehicle should provide a more constistent connection. We see often electrical troubleshooting issues are caused by poor ground connections often due to corrosion, stacked rings, etc. and terminating to the frame increases the chance...

  • Does Winch Vehicle Wiring Kit # BDW20207 Not Connected to Winch Drain Vehicle Battery
    Having a winch wiring kit like the part # BDW20207 installed on a truck would not drain the battery at all. There would need to be something connected to the wires that draws current for the battery to drain. So if you installed this kit and didn't have a winch wired up this wouldn't cause your battery to drain.

  • Will the Bulldog Winch Rear Wiring Kit Work With a Smittybilt Winch
    The Bulldog Winch Rear Wiring Kit part # BDW20207 is not specific to any one particular winch. The spades will crimp onto the leads of the winch wires and then insert into the connector. Therefore, yes the Bulldog Winch Rear Wiring Kit will work with a Smittybilt Winch.

  • Amperage Rating for the Bulldog Winch Wiring Kit BDW20207
    I spoke with my contact at Bulldog Winch and he said that the # BDW20207 is designed for a 12 volt system that sees intermittent 400 amp use. He said that if you are looking for an alternative application for this it would be easier if you gave us that info and we can see if this would work.

  • What Type of Battery is Needed for Powering Trailer Winch and Way to Charge it
    You would want to go with a deep cell battery. Having a battery larger than you would need would be the way to go as having a battery that is similarly rated as the draw of the winch will drain it quickly. We don't carry any deep cell batteries but you should have no problem tracking one down. 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 tow vehicle you will need to wire it directly with the Trailer Wiring...

  • How to Pick Out Electric Winch Wiring Kit for a Vehicle
    The Superwinch vehicle wiring kit you would need is going to depend on the rating of the winch you have. If it is up to a 4k winch you would want the part # BDW20043. If it was up to a 16.5k winch you instead would want the part # BDW20207.

  • Does Bulldog Winch 1.8 hp Trailer Winch # BDW15019 Have to Wire to Trailer Battery
    The Bulldog Winch 1.8 hp Trailer Winch # BDW15019 draws way too much amperage to be powered by the 12 volt power circuit of a 7-way. If you wanted to power it from the battery of your tow vehicle instead all you would need is the wiring kit part # BDW20207. No trailer winch would be able to be powered by the 7-way 12 volt circuit. Otherwise you would need to have a battery on your trailer.

  • Recommended Wiring for Electric Trailer Winch
    The Bulldog Winch Trailer Winch # BDW10029 will either connect directly to a trailer battery or you can use a wiring connection from your truck battery as you mentioned. For that application, I recommend the Bulldog Winch Rear Wiring Kit - Quick Connect to Terminal End - 2 Gauge - 24' Long # BDW20207. I've attached a video of this installation to assist. This wiring will allow you to use your vehicle battery to quickly and easily power your trailer winch when needed and will allow...

  • How Does a Winch in a Utility Trailer Normally Get Powered
    The Bulldog winch part # BDW15008 can be used in your utility trailer but it would draw more amperage than what your 7-way power circuit is rated for. Most likely your truck has a 40 amp fuse protecting it's 12 volt circuit and this winch draws up to 120 amps at capacity. So the solution is a wiring kit that can carry the higher amperage needed like with the part # BDW20207 which is a 24 foot long 2 gauge wiring kit that runs to the vehicle battery. This allows the winch to draw power...

  • Recommendation For Powering a Trailer Mounted 12,000LB Winch
    Rather than adding an additional battery on your 18' car hauler trailer, I recommend using a Rear Wiring Kit # BDW20207 to power the Winch # BDW10040. This will allow you to use the truck battery to power the winch and the alternator on your truck is capable of recharging the battery much faster than the charge line used on the 7-way.

  • Can The Anderson 175 Amp Disconnects In Kit BDW20207, Handle The Power Of A Bulldog Winch
    I spoke to someone at Bulldog Winch and they said the reason the Anderson 175 amp disconnects can work in the Bulldog Winch Rear Wiring Kit, part # BDW20207, is because a winch is used intermittently. He said while the winch can draw up to 400 amps, on average you will only draw around 200 amps. He did acknowledge if you used your winch at full power for an extended period of time, the disconnects would be an issue. But most people will not use their winch in this manner. I have included...

  • What Gauge Wire Is Recommended for Use with the Quick Disconnects part # BDW20133
    We don't sell the wire alone, but you will need to get sections of 2 gauge wire to use with the Quick Disconnects part # SW2236 that you referenced. The terminal contacts will need to be soldered to the wire. If you want the wire with disconnects, then the part # BDW20207 will serve you well. You can shorten the wire and use the remaining length for the other side of the connection if desired.

  • Why Does the Bulldog Winch Rear Wiring Kit Ground To the Battery and Not the Frame
    In regards to the Bulldog Winch Rear Wiring Kit part # BDW20207, the length of ground wire is included to ensure a good ground on every application. The kits are not tailor made to any one particular application and not all customers will have a good spot to ground the winch x amount of feet away from the rear bumper. The connection to the battery takes this out of the equation and ensures you don't have intermittent function issues caused by a poor ground. If you want to ground the wire...

  • Availability of Wiring Kit for Running to Trailer that Has 2 AWG Wire
    We have winch wiring kits like the part # BDW20207 that have 2 AWG wire run to a quick disconnect type of connector. Using this thicker gauge wire will only be beneficial to run power to your trailer. Another option is the 3 AWG # BDW20043. One end would wire to the battery/alternator of your truck and the other connector to the trailer.

  • Wiring Kits for Power Winch at Rear of Vehicle/Trailer
    Winches draw quite a bit of amperage so for a kit that will be rated for that type of amerage draw we have the heavy gauge kit part # BDW20043 for up to a 4k winch, or if you have a higher rated winch we have the # BDW20207 for up to 16.5k. These kits run all the way up to the battery to power the winch.

  • Wiring Needed to Power Dump Trailer Directly From Truck Battery
    A 24 foot power and ground wire kit part # BDW20207 would be a great solution for the wiring on the vehicle side of the setup and then from there to the battery on the trailer we have shorter kits like the part # BDW20205.

  • Quick Disconnect Wiring Recommendation For Trailer-Mounted Pump Behind 2012 Ford F-150
    When you use the power wire on the harness at the rear of your 2012 Ford F-150, you may have some issues with it blowing fuses when you turn the diesel fuel vault pump on. Many times a pump or other accessories will have a power surge and that is too much for the harness designed for a trailer connection. It is not recommended to use the harness, but we may have a solution for you that will work. I recommend the Trailer And Vehicle Wiring Kit, part # BDW20207. This kit has the vehicle...

  • Wiring Kit for Powering Winch at Rear of Vehicle with 2 Gauge Wire
    You basically just created a winch wiring kit like the # BDW20207 which is 24 feet of 2 gauge wire just like what you have so what you did was a great route to go. Some might run it to the output pin of the alternator but it's basically all the same.

  • Recommended Ways to Power a Winch on a Trailer
    The best way to power the winch on your trailer would be to have a large battery installed on the trailer that will power the winch and then use the 12 volt accessory circuit from the 7-way on your truck to put a maintenance charge on the battery. Or if you have a winch with up to a 16.5k capacity you could get the Trailer and Vehicle Electric Winch Wiring Kit, # BDW20207. This sounds more like what you would want. This will run a power wire from the battery of your vehicle all the way...

  • Winch Wiring Recommendation for a Ford F150 at the Rear of the Truck
    The issue you most likely ran into is that winches draw way more amperage than what the 12 volt accessory wire of your 7-way can provide. You would have needed something like the part # BDW20207 to power your winch. Your going to have to start checking all the fuses in the fuse boxes under the hood of your 2006 Ford F150. It's hard to say exactly what fuse or relay blew but it could be more than one. I would check ignition fuses first. If you can't figure it out you may need to tow the...
