Video Transcript for Blue Ox Accessories and Parts BX88254 Review

Today we're going to show you the Blue Ox seven wire to four wire coiled electrical cord, part number BX88254. We have it together here and you can see that our coils are tied together, and it's just about a foot long. This will actually expand or stretch out to about seven feet. Now we'll take a look at its seven-pole end here. This is designed to work with your RV. The other end is designed to plug into your car that you're towing behind the RV.

It also comes with a provided four-pole connector as well. Now this does not come with a bracket to hold it in place, or the hardware, so you need to supply that on your own. Now all the wires and cables are encased in a silicone-based material. That will finish it for the Blue Box seven to four-way coiled electrical cord, part number BX88254. .

Blue Ox 7-Wire to 4-Wire, Coiled Electrical Cord - 7' Long - BX88254

Average Customer Rating:  4.8 out of 5 stars   (68 Customer Reviews)

Quickly and easily connect your towed vehicle to your RV with this durable, insulated electrical cable. Includes car-side, 4-way round plug.


etrailer had what I was looking for. Ordering was easy and owns arrived a promised. I'll be back to buy more.


We've owned a few of these, and they've been fine. Our hook-up requires that the cord be pulled pretty tight, and we use small bungees at both ends to keep it plugged in when traveling, and to keep it from dragging down the road if it should become detached. We've had it happen, and the cord was ruined.
We would like to find a longer one but have not seen such an item for sale. A wire came loose a few months back, in the 'tow car' end. A simple fix.
These are the best cords we've found.

The Blue Ox BX88254 stretches to 7 feet long, but Hopkins offers a longer version, part # HM47043
Hopkins Endurance Flex-Coil Trailer Connector Adapter w/ Nite-Glow - 7-Pole to 4-Pole - 8' Long
which stretches to 8 feet long.

Very well.
Robert - 08/22/2019


Worked great no problems


Don’t blame etrailer, but this Blue Ox cord has no instructions for wiring the receptacle. Other than that, the product is great!!!


We were having a hard time finding a replacement cord to connect our motor home to our Jeep. Jeep dealer was not real helpful. I came across this site, they had what I needed shipped it promptly. It is great quality and works well. Even better than the previous one I had which did come from the Jeep dealer.

Great! No problems.
James D - 06/27/2021


As shipping


Well made product. Received on time as-promised, well packaged and no damage. Good craftsmanship and quality components very evident and it works as advertised.
eTrailer is a great company to do business with. Their internet site os well designed, fast and accurate with great follow-up and attention to the customer. I have completed business with them for over a few years now and never had a disappointment.
Recommend them all the time.

Using this product for over a year now and It is working great... as it should. I STILL like doing business with eTrailer.
Bob S - 08/01/2016


I ordered on Sunday and received on Thursday! Your tracking was excellent and your customer service is top notch! Thank you so much Etrailer for being there! I will highly recommend you!


We were glad to be able to find this item. First we drove out to Wentzville thinking the store would be open. Sure hope it opens back up in the future.
You have many items needed by motor home owners and we intend to tell our friends to remember about your services.


Looks like excellent quality, but pricey for a patch cord.


This was just what I was looking for and has worked great since I bought it a year. Really like the length for my motorhome-car connection; easy to install each time I get ready to hit the road. Thought about purchasing a second one to have on hand in case of an emergency.

This product is still working like it did when purchased. It shows no signs of wear...only road dirt and grime. Glad I purchased it.
Kent W - 09/07/2017


Would have given it 4 stars had it came with wiring instructions for the connector


allows me to quickly and easily go from the 7 wire plug on my motorhome to the 4 wire end on the light wiring harness I installed on my tow car. Good sturdy component.


I am very happy with my order from etrailer. I received the Blue Ox set up for my Jeep Wrangler and all were installed without a problem. Since, I have referred my friends to etrailer.


Fits perfectly would’ve loved it if some kind of wiring diagram for a 4pin round trailer plug was included



These folks are EXCELLENT!!!
Great prices (better than other web stores in many cases) and their Customer Service is OUTSTANDING, seriously. My order was not huge but they were in constant contact with me, even on a Sunday!, letting me know where things stood and even following up after delivery to make sure I was happy... Where do you get that kind of service today?? I highly recommend Great folks!


Everything looks great. Excellent phone service.


Excellent electrical cord


I purchased this item as a replacement and it works very well. I prefer the coiled cord over what I had before. I would recommend this item.


Good quality product and fast delivery. Just what I needed to connect Motor home to tow vehicle.


Haven’t used it yet but I am sure it will work fine.


This blue cable had been damaged from squirrels. Thanks etrailer for making this a fast and easy purchase.


Ordergin this electical connector is the first step in preparing my car for towing. It was the right plug for the existing socket that is already on my RV.


Standard electrical cable from motorhome to Jeep for towing.


Good web site easy to use

  • How to Wire the 4-Way Round Socket for the Blue Ox 7-Wire to 4-Wire Adapter # BX88254
    There are so many different diagrams on how to wire a 4-way round trailer connector because a standard has not been set on how to wire this type of trailer connector. This is likely because 4-way round trailer connectors are not very common. I spoke with my contact at Blue Ox to determine how they wired their 7-Wire to 4-Wire Adapter, # BX88254, that you are planning on using. When looking at the front of the socket, wire the 4-way round socket as follows - Top Left - Left stop/turn,...

  • Installing/Repairing the Blue Ox Coiled Electrical Cord # BX88254 on a 2012 Ford Focus
    The Blue Ox 7-Wire to 4-Wire, Coiled Electrical Cord # BX88254 will work with your current setup if you are wanting to replace your current wiring. I do have a way for you to accurately recommend all of your current wiring as well if that was your concern. Attached is a photo of what pinout should be for your 4-Way. Simply apply 12V power to the loose wires to see what light circuit they run to and then connect them accordingly. You can use the 7-Way photo that I linked so that you know...

  • Recommended Tow Bar Wiring for 1989 Jeep YJ with Wiring and 4-Way Round Already Installed
    For a tow bar wiring kit that will allow your 1989 Jeep YJ to accept the Escalade's tail, brake and turn signal lights, I recommend the Blue Ox 7-Wire to 4-Wire # BX88254. Since you already have the wiring and round 4-Way connector installed on the Jeep, this will be all you need to connect from the Jeep to the 7-Way on your Escalade. I have attached a short video demonstration on this product for you to check out.

However, this is a universal bulb and socket kit that works via plugs and sockets mounted inside the tail lights of your vehicle. I attached an installation video for a Honda Pilot and the process should be very similar for your Honda Fit. You will also need to add a 4-Way round wiring kit # BX88254 to run power from the 7-way connector on your RV to your...

  • Black 7-Wire to 4-Wire Coiled Electrical Cable
    The Blue Ox 7-Wire to 4-Wire Coiled Electrical Cord # BX88254 only comes in blue. My understanding is that these types of cords typically come in high visibility colors so that they're easy to notice if something is hanging down while towing. If you wanted to go with an uncoiled cord, we do have a black one available in the Hopkins Tow Bar Extension Cord # HM47047 that provides the same connection.

  • Umbilical Extension Cable Recommendation for 7-Way to Tow Vehicle with 4 or 6 Way Round
    How many pins does the connector have on your tow vehicle? If there are six total pins including the center pin you would want the part # BX88206. If instead there are 4 pins on the smaller connector you would want the part # BX88254.

  • Wiring to Connect Motorhome to 2010 Honda Fit That's Being Flat Towed
    The base plate has mounting points for either a 6 or 4 way round connector to attach, but the connectors aren't included with the base plates. I'd recommend cutting off the 4-pole flat provided by the Hopkins # HM56302 flat towing wiring harness and installing the 4 pole round connector provided with the 7-foot long Blue Ox 7-way to 4-pole round cord, part # BX88254. I've linked you to some of our flat towing FAQ articles.

  • Can 4-Pole Round Connector Be Installed on Hopkins Flat Towing Wiring Harness on 2015 Wrangler
    That's correct. The Blue Ox # BX88254 Coiled Electrical Cord does included a 4-pole round connector. You can simply cut off the 4-pole flat on the Hopkins wiring harness and replace it with the 4-pole round connector. If you use the Blue Ox # BX1126 base plate, it actually has a mount for the connector built onto it, as shown in the provided photo. I'll link you to some FAQ articles you might find helpful, as well as to videos showing the Hopkins wiring harness and the base plate kit...

  • Equipment Needed to Flat Tow a 2016 Subaru Forester
    For a base plate, Blue Ox offers part # BX3619. The Blue Ox Alpha, part # BX7380 would be a good choice for a tow bar. The Alpha offers swiveling and self aligning arms that make hooking up the dinghy easy, even on uneven pavement when the dinghy isn't perfectly lined up with the motorhome. The tow bar also includes safety cables. For a lighting solution, I'd recommend a bulb and socket kit like the Blue Ox # BX8869. You'll also need an umbilical like the Blue Ox # BX88254. For a supplemental...

  • Can the LED Bulb and Socket Kit # BX88267 be Installed on a 2009 Subaru Forester for Flat Towing
    We do have an LED wiring kit just like the Kit # BX8869 that you referenced. It is found as part # BX88267 on our site. You can use the LED kit if your 2009 Subaru Forester does not have LED tail lights and if each tail light housing has enough room for an extra bulb and socket. It could be that there is no room for an extra bulb and socket which would be why the Roadmaster Kit # RM-152-LED isn't confirmed to fit. If you do have LED tail lights (or you don't have enough room for an extra...

  • Equipment and Modification Needed to Flat Tow 2000 Ford F150 Behind RV
    According to my research, your 2000 Ford F150 would require a driveshaft disconnect in order to be flat towed without damaging the transmission. Once a driveshaft disconnect has been installed, you'd need a base plate kit, a tow bar, safety cables, an electrical connection to power the vehicle's taillights and a supplemental braking system. I really like the Blue Ox base plate/towbar systems. They are very well thought out, and I find their base plates to be easier to use. For a base...

  • Necessary Equipment to Flat tow 2003 Subaru Baja Behind an RV
    Before attempting to flat tow your vehicle, I'd recommend checking the owner's manual or with Subaru about any procedures or modifications required to flat tow the vehicle. I was unable to access an online copy of your owner's manual. Usually, manual transmission vehicles can be flat towed without modification, but if the vehicle is AWD or has an automatic transmission, the vehicle will often need some modification. To flat tow the vehicle, you'll need base plates, a tow bar, safety cables,...

  • Can Front Mounted Hitch Be Used to Flat Tow 2004 Toyota Tacoma
    A front mounted receiver hitch is not designed to be used as an attachment point when the vehicle is being flat towed. To flat tow your 2004 Tacoma, a tow bar base plate must be used. I'd recommend the Blue Ox # BX3728 base plates and the # BX7380 Alpha tow bar, which includes safety cables. For a lighting solution, I'd recommend the # RM-155 bulb and socket taillight wiring kit. The kit provides an extra set of bulbs that install in the rear taillight assemblies. This kit won't require...

  • Missing Connectors for Blue Ox 7-Wire to 4-Wire Coiled Electrical Cord # BX88254
    I'm going to assume that you have a Blue Ox coiled electrical cord, like part # BX88254, which has a 7-way for your motorhome. To replace the connector on the front of the towed vehicle you can use part # PK11410, and for the connectors on the cord, # PK11409 for 4-way and # PK12706 for 7-way. I have included a picture for you which shows each style of connector and part number.

I was unable to determine how the Winch support you have on your truck is mounted but you can look at the attached installation instruction for the base plates to see if there will be an issue with both installed.

    I am glad you emailed us because there are some things that you need to be aware of. First, the Tow Ready tow bar, # 63180 is only rated for 5,000 pounds and your 1996 Chevy Silverado could easily exceed this capacity. The other problem with the tow bar is that it is only rated for a maximum speed of 45 miles per hour. We need to get you a proper set up.
