Blue Ox Tow Bar Wiring - BX8848
- Diode Kit
- Splices into Vehicle Wiring
- Tail Light Mount
- Universal
- Blue Ox
This wiring kit carries brake and turn signals from your motorhome to your towed car while you're flat towing. Diodes protect your car from damage from electrical feedback.
Features:
- Connects RV's brake and turn signal lights to towed car's tail lights
- Prevents feedback that can damage your vehicle's electrical components
- Includes:
- 26' 4-Wire harness
- 4 Diodes
- Wiring, butt connectors, ring terminal, and spade connectors
- Made in the USA
- 1-Year warranty
Notes:
"Don't be intimidated by diodes: if you can strip and crimp wire, this installation will be no problem."
Combined Lighting System vs Separate Lighting System
A combined lighting system, or 2-wire system, uses the same light bulb to signal both braking and turning. (In other words, the car signals a turn by flashing the brake light.)
A separate lighting system, or 3-wire system, has the brake signal and the turn signal light up independently of each other. Typically, the turn signal is amber.
To keep the separate lighting system on your car functioning properly while you're flat towing, add a wiring converter (118158 - sold separately) and 2 additional diodes.
Do I Need a Brake Light Relay?
If the engine is off and your car's brake lights illuminate when you press the brake pedal, you need to install a brake light relay (RM-88400 - sold separately) with this kit. Without a relay, your car's brake signal will override the turn signal sent by the RV when you are slowing down to make a turn, creating a potentially dangerous situation. Other drivers will see that you're slowing down, but not that you're making a turn. With a brake light relay, you can signal both and travel safely.

Took a bit to get to the rear lights on the wrx - trim pieces etc. But once there the instructions were easy to follow and the lights work great!

I returned this item in favor of the Curt Bronco flat tow light kit. The Curt kit is far superior to the Blue Ox kit. The Curt kit is totally plug and play no diodes to deal with. I would have bought the Curt kit from you if you sold it. You would be better served with the Curt kit.
by: Travis02/02/2024
easy install. I had to use my red connectors because I didn't want the blue ones getting a loose connection with the small gauge wire.

Installed on new Ford Maverick Hybrid pickup. So far so good. Survived 8000 mile West coast trip with no problems.

Had everything I needed to wire my Jeep Grand Cherokee. YouTube videos exist to help. There some surprisingly difficult places to route the wires along the frame.

Perfect for my application on a 2001 GMC Sierra 1500 HD.

I have inventory all packages and everything is here a ready for installation. All parts are quality and instructions are very clear.
by: Deborah04/20/2023
eTrailer was very helpful in choosing the correct hitch for our rv and car. They also provided a special brake application in the car that makes it super easy for toad braking.
I am 72, and I hook up this toad and pull it with confidence. The instructions to hook up the toad was presented with ease. They knew exactly what they were doing, and we didn't rush through the demonstration. I would recommend eTrailer to anyone.
by: Ed06/02/2023
Great quality product and I like that they supply the few extra feet of brown & green wire to go between tail lights. The other brand I bought from you did not and I had to go to a big box store to buy another roll of trailer wire to complete the installation on my last vehicle.

We love the Blue Ox kit! Pretty simple to use.

The Blue Ox Tow Bar Wiring Kit - 4 Diodes work exactly as advertised. The diodes work to separate the harness from the system, so there is no back feed to the car's electrical system when the brakes, lights, or turn signals are activated in the motorhome. The car's rear lights are activated in sync with the motorhome lights. So much easier to hook up the "toad" to the motorhome using this harness.
Installation when very easy, after I figured out how to access the taillights on the 2019 Chevy Traverse, but now that's another story.
I would highly recommend this harness.

Dealing with etrailer for several years, always fair price, prompt service & communication regarding orders. Also Excellent videos that are extremely valuable.
by: Michael 03/15/2021
Toughest part of installing this system was determining the best and neatest way to route the wires from front of the vehicle to the rear. Works great but does not provide wiring to run the third/middle brake light on the towed vehicle which in my case is a 2010 Chevy HHR. I subsequently opted to install a system which constantly charges the HHR battery from the RV power which allows me to keep the HHR power on so when the Brake-Buddy applies the brakes all the brake lights illuminate. Otherwise a perfectly good system with everything you need for an easy install.

It makes wire easy
by: Jeff07/05/2020
Went well except for instructions installing baseplate for my 2017 Silverado. After grille removal was not close to the instructions. I [looked for installation videos for] 2018 model and instructions for grill and bumper removal was right. Nice project and saved a lot on install. etrailer is great at putting together the equipment you need. Love website to research products. Have not pulled truck any where yet. [(Covid)]
by: S.K. Nack06/10/2022
The order arrived very quickly and is all intact. The (base plate) picture quality is a little poor from Blue Ox, but I talked to Angela B. and she is emailing the instructions to me for better viewing.
I might add that Blue Ox would have charged for shipping.
Now it is time for the installation.
by: Peggy03/14/2022
Customer Service is excellent! The tow bar was delivered promptly and should work great. I didn't receive the wiring kit I ordered but when the company was contacted....they were great to work with and shipped another right away!!
by: Joseph 11/05/2021
Everything needed to provide motorhome lighting to the towed vehicle. This will NOT eliminate towed vehicle battery drain on long tows, and while many have a way to boost towed vehicle battery during tows, no one seems to have the reason for the battery drain. I thought the diodes would eliminate that problem.
by: Doug P06/29/2020
I was looking for a product that had everything I would need to do the job without having to go to local auto parts store to find special parts not usually stocked. The instructions were pretty good but could have been better with a couple of photos and details in the routing near the engine compartment and wire loom for added protection in the area. The finished look is well hidden as it should be and not hard to install.
by: Robert03/16/2022
Still using magnetic lights. Haven't installed wiring kit yet.
by: Carol03/24/2023
Justin was very nice and helpful over the phone, no pictures yet because it's kind of cold in Massachusetts so I will have to wait until it's a little warmer. I will install it myself. This will be the fifth vehicle I've done this on, just follow the directions.
by: Ardell07/20/2020
I am new to the world of towing a vehicle behind an RV and found a lot of articles/videos on the interweb, not having a clue what to expect except what I've read and watched on the web I reached out to etrailer.com and Courtney B answered all my questions, removed all my doubts of what i was doing and provided everything we needed in the timeframe we needed it at a reasonable price! I can't thank her or etrailer enough!!! I will buy here again and trust in they're how to videos without question. Thank you

See what our Experts say about this Blue Ox Tow Bar Wiring
- Will The Blue Ox Tow Bar Wiring Kit # BX8848 Work With 6-Volt Systems Hey John, I confirmed with Blue Ox that the diodes included with the Blue Ox Tow Bar Wiring Kit # BX8848 are compatible with 6v systems.
view full answer... - Will the Blue Ox Diode Kit 8848 Fit a 2013 Ford C-MaxYes, for your 2013 Ford C-Max the Blue Ox Tow Bar lighting kit part # BX8848 has been confirmed as a fit. I attached a link to the install instructions plus a link to a help article page on installing kits like this.
view full answer... - How Does Blue Ox Diode Kit BX8848 Install on Vehicle With Separate Turn Signals TaillightsOn vehicles that have separate stoplights from turn signals you can wire up a diode kit like the part # BX8848 still but what you have to do is basically make the stoplights of the vehicle function as both the stop lights and turn signals since that is how the diode kit is wired. Trailer wiring puts these circuits on same wire which is why it's easiest to do diode tow bar wiring the same. Basically your current stoplights will still function as stoplights but they will flash with the blinker...
view full answer... - How to Find Wire Colors for Blue Ox Tow Bar Wiring Kit on 2022 Jeep GladiatorIn regards to installing a diode wiring harness like the Blue Ox Tow Bar Wiring Kit part # BX8848 on a 2022 Jeep Gladiator, you'll need to test the circuits to ensure you are selecting the correct wires. The wire colors can change from year to year and with certain options. In the past, the driver side has been solid yellow for the stop/turn and the passenger side has also been solid yellow or solid green for the stop/turn. The running light wire has been solid white or white/orange. This...
view full answer... - Troubleshooting Diode Trailer Wiring Installed on Vehicle Where Turn Signal Flashes Both SidesIt sounds like you have the turn signal and running light circuits ran backwards so that when either blinker circuit is activated you end up with both lights flashing. This is because the running lights run to both sides of the vehicle and the stop/turn circuits go to each side specifically.

- Tail Light Wiring Kit for a 2019 Jeep Grand Cherokee I just spoke with my rep at Blue Ox and the Blue Ox Tail Light Wiring Kit for Towed Vehicles item # BX88267 will not fit and neither will any other bulb kit. You need to use the Blue Ox Tow Bar Wiring Kit item # BX8848 because your 2019 Jeep Cherokee has LED tail lights. You can not drill a hole into the back side of an LED light as it will be ruined.
view full answer... - Will Blue Ox Tow Bar Wiring Kit Work on 2020 Jeep Cherokee with Factory Tow PackageYes, the Blue Ox Tow Bar Wiring Kit part # BX8848 will work on a 2020 Jeep Cherokee with the factory tow package, there will be no interference between systems. Please note, this is not a complete setup as you'll still need the umbilical which connects the toad and motorhome. I recommend the Blue Ox 7-Wire to 6-Wire, Coiled Electrical Cord part # BX88206 for this.
view full answer... - Is the Replacement 6-Amp Diode for Blue Ox Tow Bar Wiring Kit a Fit For a 2019 Chevrolet EquinoxThe Replacement 6-Amp Diode # BX8864 is a replacement diode for the Blue Ox Tow Bar Wiring Kit # BX8848 which can be used with your 2019 Chevrolet Equinox with LED lights.
view full answer... - Recommended Circuit Tester With Buzzer And LightIn the installation video for Blue Ox Tow Bar Wiring Kit # BX8848 you can see the circuit tester # PTW2993 being used. This is a heavy-duty tool that comes in handy when checking circuits with up to 28V. It features a light and a buzzer to verify continuity in a circuit. I have attached a demonstration video for this tester.
view full answer... - Diode Tow Bar Wiring Kit Installation Video for a 2014 Jeep CherokeeYes, the Roadmaster Tow Bar Wiring Harness part # RM-154 would install in the exact same way as the Blue Ox Wiring Kit part # BX8848 that you have, so the video you referenced that I attached to the right would work as a guide.
view full answer... - Comparing Roadmaster RM-154 and Blue Ox BX8848 Flat Towing Diode KitsThe Roadmaster hardwired diode kit # RM-154 for flat towing a car will not differ much from a similar kit from another maker, such as Blue Ox kit # BX8848. But since the Roadmaster kit includes a protective wire loom and has been highly-rated by many more users, I would opt for the Roadmaster kit # RM-154. I linked a series of helpful articles concerning tow bar wiring options as well as installation videos for both kits.
view full answer... - How to Connect Tow Bar Wiring to Correct Tail Light Functions on a 2013 Mini Cooper SThanks for reaching out, Adele! To install the Blue Ox Tow Bar Wiring Kit # BX8848 to the correct wires you need to use a circuit tester like part # PTW2993 to test and confirm the correct functions to connect to. Unfortunately I don't have a pinout diagram of the lights on your 2013 Mini Cooper S so the only way to figure this one out is to test the wires/pins individually and then splice in that way.
view full answer... - Installation of Blue Ox Tow Bar Wiring KitI suggest you use a circuit tester such as the # PTW2993 or a multi meter to identify the wires in your Jeep's circuit. Please see the attached link to installation instructions video that will provide visual guidance to installation of the Blue Ox Tow Bar Wiring Kit, # BX8848.

Check out the video linked below for more details on this product. Note that to tow your 2020 GMC Sierra 2500, you also need a tow bar, safety cables, base plate kit, and a supplemental braking system. Here's a quick recommendation for each component: - Tow Bar: # BX7380 (includes safety cables) - Base Plate: # BX1739 - Braking System: # BLU37TR
view full answer... - Why is RoadMaster Tail Light Wiring Kit # RM-155 Not Recommended For a 2011 Chevrolet Malibu LTNeither one of our manufacturers, RoadMaster or Blue Ox, recommend to use the bulb and socket type of lighting when flat towing a 2011 Chevrolet Mailbu LT. Usually it is because of limited space in the taillight housing that does not allow the bulb and socket to fit properly. We go by what the manufacturers recommend, since they have already done a test fit on the vehicle. The RoadMaster Diode Wiring Kit, part # RM-154, or the Blue Ox Wiring Kit, part # BX8848 is recommended for your Malibu. I...

This is the nicest tow bar around so you'll really like it and it comes with safety cables.

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.
