Video Transcript for Blue Ox 7 to 4 Wire Coiled Electrical Cord Review

Today we're going to be taking a look at the Blue Ox 7-wire to 4-wire coiled electrical cord, that's seven feet long. That's going to be part number BX88254. Here's where our extension cord looks like when it's fully installed. And this is going to allow us to hook up our RV to our towed vehicle, and have all the required lights. Now, our extension cord can be used in multiple different types of towing applications. On one end, we're going to have a 7-pole round connector. And on the other end, we're going to have a 4-pole round connector.

Now, our coiled cable can be stretched out to seven feet long, but at the same time, it'll retract back to prevent any dragging or tangling when we're going down the road. And the silicone encased wire's going to help protect our connectors, as well as keep out the moisture and prevent corrosion. We come to the back of our RV here, and we find our 7-way plug, find the end with the 7-way on our coiled extension cord, and we can plug it in. Now, we can take our 4-pole round back to the vehicle. Now, we here we have our 4-pole mounted to our bumper and this bracket right here, the vehicle end of the socket, is included in our kit. Now, the bracket, you will need to buy separately to mount your wiring to your vehicle. Now, we can simply open up the dust cover, and plug it in, and we're ready to hit the road.

Here on the back side, we have our wiring ran. Now, I do want to mention, you need to have the existing wiring ready on your towed vehicle, for the extension cord to work. Now, with the rest of our connections made, and everything secure, we're ready to hit the road. And that will finish up our look at the Blue Ox 7- to 4-wire coiled electrical cord, that's seven feet long. Part number BX88254.

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. 556516

  • Wiring Diagram for Blue Ox 4-Way Round Connector
  • The Replacement 4-Wire Plug for Blue Ox Coiled Electrical Cord - Vehicle End - Qty 1 # 294-0805 is wired as the diagram shows. This is the color and function from the back of the connection where the wires to your towed vehicle attach. I've also attached a similar installation video to assist. You can use the Blue Ox 7-Wire to 4-Wire, Coiled Electrical Cord - 7' Long # BX88254.

However, this is a universal bulb and socket kit that works via plugs and sockets mounted inside the tail lights of your vehicle.

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...

  • 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.

  • Parts Needed to Flat Tow 2005 Chevy Silverado 1500 4WD
  • Flat towing safely and legally requires a few components, including the tow bar, safety cables, a wiring/lighting kit, a braking system and base plates on the towed vehicle. Sometimes a wiring extension and high/low hitch adapter are needed too. The hitch adapter is required to keep the tow bar near level when it is connected; your large tires and lift may well require one of these. Please refer to the linked help articles on flat towing and hitch adapters. You'll also want to check your...

  • 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 # BX7365 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...

  • 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.

  • 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,...

  • The discontinued Roadmaster # 5250 tow bar is compatible with EZ4 style base plates like the # RM-521559-4. In addition to the tow bar and base plates, you will also need safety cables, a lighting solution and a supplemental braking system (required by law in most states). If you prefer a coiled safety cable, the # RM-643 is a good choice. For a straight cable, I would recommend # RM-645. If you do not already have your CR-V wired, the Roadmaster Bulb and Socket Kit, part # RM-155...

The easiest way to find out if you need a relay is to turn the engine off and when pushing the brake pedal see if the brake lights come on. If they do, then a brake relay switch is needed. from my research it does not appear you need a brake light relay on your CR-V, but you can check to make sure.
