Video Transcript for Blue Ox Tow Bar Wiring - Bypasses Vehicle Wiring - BX8869 Review

Today we're going to be taking a look at the Blue Ox Tail Light Wiring Kit. This wiring kit allows you to get the signal lights needed for flat towing without tapping into your towed vehicle's electrical system. It provides brake signal, running, and signal lights, and it runs beneath the vehicle completely and connects to your RV so it bypasses the towed vehicle's electrical system all the way. The bulbs and sockets are going to mount inside your vehicle's tail lights. To get these mounted in the tail lights you will need to use a 1" diameter hole saw, that's indicated in the included instructions. It does come with detailed installation instructions to help walk you through the entire process step-by-step. Everything here on the table is what you're going to get.

You're going to get two lights, two sockets, you're going to get your bundle of wiring, this is your main wiring harness. It's going to measure around 26' long. You're going to get a couple extra extension wires for the installation back at the tail light assemblies. You're going to get your ground screws, your butt connectors, and you're going to get your ring terminals. The product's also fully made in the USA, and again, it does come with detailed installation instructions to help walk you through that entire process step-by-step. These bulbs are going to sit in a really nice, it's like a J-socket ...

So you can push those down and release them as needed. It's going to use bulb number 2357. That's going to do it for today's look at the Blue Ox Tail Light Wiring Kit.

I needed to wire our ‘17 Chevrolet Sonic for towing behind our Motorhome. My local shop wanted over $xxx to install such wiring. Online I found the Blue Ox wiring kit and decided to do it myself. The kit and instructions were very complete and informative and it took me about three hours to complete the installation. The time consuming part was removing and reinstalling trim and panels to hide the wiring inside the car. The thing I like most about this kit is it’s independent of the cars wiring system and I’m very happy with it.

The wiring harness was great. Directions were very good and installation was fairly easy with few CNN if any real problems.

good product and instructions


This kit was a lifesaver. I did not want to cut in to my Fiat 500’s wiring, but I didn’t like the magnetic light set up either. This light set up was the happy medium and work’s great. Also, there is no drain on the tow car battery! I ran the wiring through the interior of my car for a really clean look.

Easy Install Light Kit!
Robert C - 12/14/2020


Great service! Product was exactly what I ordered.


Easy Peary install and has worked flawlessly for a year of travel over 8,000 miles

When it comes to wobble there are a couple of possibilities. Since this is a DIY kind of installation, the bracket that holds the bulb could be coming loose. For that we suggest using a tapping screw or some type of adhesive to prevent the wobble. The other option could be that the bulb is starting to come loose from the bracket itself. If that is the case, then we recommend pulling out the bracket and bulb to make sure that the connection is secured.

Liked the fact that I didn’t have to cut into my light system on my truck. Easy install


Order arrive on time just as ordered. All my questions were answered. Alex you did a great job. Thanks


My 2018 Honda Civic Hatchback baseplate has worked great, no "0" issues. I've towed my car over 4,000 miles and the baseplate is as tight as the day I put it on. Great product......


Autum is the best..She is very knowledgeable and dedicated .Every time I call she spends so much time with me to make sure i get the right item for my project.Love her...She needs a raise... Thanks..


I put this base plate on with the assistance of my wife very easy to install. Do recommend the video to install


We bought the Blue Ox Patriot Braking System from etrailer based on their reviews and their reputation of standing behind their products and being available for questions. We also bought the Blue Ox Tow Bar and Base Plate which I installed myself on our 2016 Fiat Pop. It is such a small and light car that we could probably tow it in most states without a braking system, but we didn't want to take a chance. Better safe than sorry. The system works great. Fortunately, I did not have any issues with the tow bar install except for drilling two holes through the bumper area, however that was my fault (dull bit). etrailer is E-excellent!


This set up works great on my PT Crusier. I haven't had an problems.


Got the products quickly and with no issues. Tail light wiring kit Installation was a few days later due to schedule but the installation went well and the videos of installation steps was very helpful. Use caution when installing the bulb into the tail light assembly. The manufacturer says to use a 1" hole saw. The hole and the bulb are very close in size and can be pretty loose in the hole. You can bend some of the tabs out to make it hold center then apply the silicone sealer.
Hitch receiver and lock - excellent.


I ordered several items to equip my Honda CRV for towing....BlueOx baseplate, lighting kit and a receiver tube (to carry bicycles). Good prices and expeditious shipping. Can't complain about anything....was very happy with their customer service. They certainly will be my go-to source if I need anything in the way of towing or hitch equipment.


The BX8869 I ordered is a wiring kit used for towing a 2005-07 FORD FOCUS ST. Product arrived in an expedient fashion and the installation was fairly straight forward although finding a way through the firewall seemed dubious at best. Ran the wiring through the engine bay under the vehicle up to the rear tail light housings.. Keeping the wiring up and safe was a bit of a challenge. Based on the experience on the whole I would have no hesitation recommending etrailer to family or friends for quality products at very competitive prices.


Couldn't install it... there simply wasn't space in the tail light housing on my Honda Fit to include the additional bulbs.


John at was very friendly and helpful. I bought what I needed at the lowest price I found on the internet and I received my delivery in just a few days, much faster than I anticipated. The baseplate was pretty easy to install on my 2021 Jeep Grand Cherokee but everything was exactly as the directions stated.


Blue Ox is top of the line and this wiring kit is easy to install. With the included instructions and the eTrailer YouTube video, anyone can complete the install with basic tools.

Overall, eTrailer customer service, products, and shipping is top of the line. I ordered products via phone and their website and both experiences were exceptional. There pricing is better than any other site or shop. eTrailer is now my new go-to site for anything I need. Thanks guys.


This is the second time I’ve used this kit on a vehicle. On my 2019 Subaru Crosstrek, the installation required removing trim pieces from the drivers side foot well, door sills, and the rear cargo area. It was more complex than my 1985 Jeep CJ7, but it’s worth it not to have to deal with diode kits etc. the key attribute with this kind of work is planning and patience. The instructions are clear, and the kit works as stated


This is a great kit to add rear lights to a Ford Focus because you have to remove the negative battery cable for towing. There is more then enough wire to complete the job of wiring the lights from the rear of the car to the front for a permanent installation.


Base plates went on after going through several drill bits. The examples for installing safety cables did not apply to my vehicle but they are on the bottom of the frame. Installing the tail light bulbs was difficult without a one inch hole saw (couldn't find one). Had to trim fascia to install wire receiver. Overall ok.


Finished the install this weekend of BX8869 wiring kit along with the final hookup with the roadmaster tow bar. Everything went exactly as shown in the directions and the video for the CMax. The video was exactly what I needed. Everything was working exactly as expected on our test drive.


Easy to install. It only works for brake lights and turn signals. It does not work for tail lights if driving in the dark.


This product worked as intended. I was able to keep the car wiring separate from the motorhome wiring, electrically. In my Saturn it was relatively easy to run the wiring and drill the new holes in the back of the rear light housings. I will use these same type of parts again if I change my towed vehicle.


I installed the wiring system on a 2015 equinox and it works great. I’m no rocket scientist but the instructions and the assistance I received from etraier made me look like one. Again it works great and I will be using etrailer again for other upgrades to my moterhome suspension system.

  • Fit of Blue Ox BX8869 Bulb and Socket Wiring Kit in Taillight Housings of 2019 Jeep Grand Cherokee
    Blue Ox does confirm that their # BX8869 Bulb and Socket kit does indeed fit in the taillight housing of a 2019 Jeep Grand Cherokee. The bulb and socket kits are a nice choice because they remain completely independent of the towed vehicle's wiring system. You will need to drill a hole in the taillight housing, but you'll be able to leave your factory taillight wiring completely intact. I've linked to a product description video for the bulb and socket kit.

  • Determining if Blue Ox Bulb and Socket Wiring Kit Will Fit 2020 Jeep Gladiator
    We haven't gotten a chance to install or talk to somebody who has installed the Blue Ox Tail Light Wiring Kit # BX8869 on the 2020 Jeep Gladiator to be able to say with certainty that it will fit or not. This is a pretty universal kit but you will want to make sure there is enough room inside the tail light housing lens for the extra bulb and socket, which measure 2 inches and 1 inch long respectively. I recommend simply measuring the space you have available behind the lens to make sure...

  • Is Brake Light Relay Needed When Installing Blue Ox Tail Light Wiring Kit # BX8869
    A brake light relay is not needed when you are using a separate bulb-and-socket taillight kit in your towed vehicle, such as Blue Ox # BX8869. The relay is needed only if you are tapping into the toad's own internal wiring with a diode kit.

  • Tow Bar Wiring Recommendation for a 2004 Volkswagen New Beetle
    I have exactly what you need. What you are describing is referred to as tow bar wiring. I did some checking and it looks like Blue Ox has confirmed the Blue Ox Tail Light Wiring Kit # BX8869 as a compatible wiring system for your 2004 VW New Beetle. To complete the wiring and allow you to connect to your tow vehicle you would also want the # BX8861. I attached a couple FAQs to the right with more info on tow bar wiring.

  • Will Blue Ox Bulb and Socket Kit Fit a 2010 Mazda5 to Tow on a Tow Dolly Behind a Motor Home
    The Blue Ox bulb and socket kit, # BX8869, will fit your 2010 Mazda5. To add a 4-way round harness you will need # BX8861. You will want to check the owners manual on the motor home to make sure you can use both connectors at the same time. Too many lights could create too much draw on the system.

    I don't see that we have made an install video for the Blue Ox Tail Light Wiring Kit - Bulb and Socket # BX8869 on your 2013 Honda Fit. However, this is a universal bulb and socket kit that works via plugs and sockets mounted inside the tail lights of your vehicle.

  • Will the Blue Ox Bulb and Socket Lighting Kit Work for Flat Towing a 2005 Chevy Colorado
    Yes, the Blue Ox Bulb and Socket Tail Light Wiring Kit, # BX8869, is confirmed to fit in the taillight housing on your 2005 Chevrolet Colorado. Along with the bulb and socket kit you will need an electrical cord and connectors to go from the towed vehicle to the motorhome. Blue Ox recommends the 4-Wire, Coiled Electrical Cord with 4-Way connectors, # BX8861 if your motorhome needs a 4-Way round connector, and the 6-Wire Coiled Electrical Cord with 6-Way round connectors, # BX8862 if your...

  • Is the Brake Buddy Supplemental Braking System Compatible with Blue Ox Base Plates?
    Yes. You will be able to use Blue Ox base plates like the # BX8869 and the Roadmaster Brake Buddy # HM39494 without compatibility issues on your 2015 Nissan Versa. For future reference, the only time you'll have issues with compatibility across flat towing components is when using tow bars and base plates that aren't from the same manufacturer; to combat this, base plate adapters are available. I've linked an article with our base plate adapter table that you might want to use if you ever...

    Yes, you can use the Roadmaster supplemental braking system # RM-9700 with the Blue Ox bulb and socket kit # BX8869. Roadmaster has their own bulb and socket kit that installs the same way as the Blue Ox. There may be other parts needed though so I would need to know the year, make, and model of the vehicle you will be flat towing to determine if there is anything else you will need.

We have installed the # RM-155 on a 2013 Honda CRV, and found that the bulbs fit perfectly in the taillight assembly.

  • Flat Towing Lighting/Wiring Kits Recommended for 2015 Jeep Wrangler JK
    Blue Ox Bulb and Socket Tail Light Wiring Kit # BX8869 is not recommended for your 2015 Jeep Wrangler JK due to too little available space inside the tail lights. Since this kit uses incandescent bulbs which generate a fair bit of heat there is a risk of damage to the light housings. The linked page displays all confirmed fits for flat towing lighting/wiring kits. The two linked articles on flat towing wiring kits may be of interest.

    In order to install the Blue Ox Tail Light Wiring Kit part # BX8869 in the back of the taillight housing on your 2017 Jeep Wrangler you will need at least 1" of space in order for the bulb and socket kit to work. I did some research and looked at a few of the taillight assemblies for your Jeep and believe you should have absolutely no problem using this kit. 1) Starting in the engine compartment of the towed vehicle, run the 26 ft. harness through the fire wall, under the driver's side...

    Yes, the Blue Ox Tail Light Wiring Kit # BX8869 will work on your 2016 Jeep Wrangler Sport but I recommend going with the Hopkins Custom Tail Light Wiring Kit # HM56200 instead because it tees in with the connectors for your tail lights instead of having to drill holes into your assemblies and risk breaking something (which isn't uncommon). If you tee in the Hopkins kit and then cut off the 4-Way connector it gives you the same wiring as the Blue Ox kit but it's a much easier and cleaner-looking...

    When using the Blue Ox Alpha Tow Bar, # BX7380, I recommend going with Base Plates, # BX1115, for your 2000 Jeep Grand Cherokee. These custom fit base plates provide attachment points for the tow bar and no adapters will be needed. If you still need lighting for the Jeep, I recommend going with the # RM-2120 light kit if you do not plan to flat tow very often. These lights will fit at the top of the rear hatch and plug straight into the 4 way on the RV so no additional wiring/connections...

  • What is the Amperage Rating for Vehicle to Vehicle Tail Light Converter # 118158
    I spoke with my contact at Tow Ready about converter # 118158. He said that at most the converter is rated for 2.1 amps per side for brake and turn signals so it would not work for you. I recommend going with a kit that bypasses the vehicle wiring such as a bulb and socket kit, # BX8869, or a magnetic kit such as # RM-2120. I have included some links to articles on tow bar wiring for you that should also help.

  • Compatibility of 1994 Honda Accord with Blue Ox Bulb and Socket Flat Towing Lighting Kit
    According to Blue Ox, the 1994 Accord wouldn't have enough room in the taillight assembly to accommodate the extra bulb needed for the # BX8869 bulb and socket kit, so it wouldn't be a good fit for your Accord. A diode kit like # 154-792-118158 would be your best choice for a permanent lighting solution, if the magnetic lamps aren't working well for you anymore. I've linked you to some helpful articles about flat towing.

    First, you will need to confirm that the vehicle is suitable for flat towing. From what I have read on page # 319 through 321 of the owners manual, your GC can be flat towed if the transfer case has a Neutral position. If your 7-way on your RV has a 12-volt power feed (typically the pin in the 1:00 position), you can use that circuit to maintain your battery, however it will not charge a discharged battery.

If it concerns you, and drilling a hole in the tail light housing is not an issue, you can definitely use a bulb kit on your TJ.

The Blue Ox Alpha, part # BX7380 would be a great choice for you. The Alpha includes safety cables, is self aligning and will easily fold up against the rear of the motor home when not in use.

The warning regarding 5,000 pounds is in reference to lower capacity tow bars, not the base plates. So you will be fine with the Aventa and these base plates. The Avail tow bar comes with safety cables so you will just need to add lighting and supplemental braking. For lighting you can use the Blue Ox bulb and socket kit # BX8869. This kit...
