Features to know about

Upgrades 4-Way Setups for More Functions: 6-Pole Round Pin Socket

If you’re adding a brake circuit, charge line, or other accessories, this 6-pole socket makes the jump from a simple 4-way connection easy. The Blue Ox 6-Pole, Round Pin, Trailer Wiring Socket gives you six pin positions to expand your setup beyond basic lighting. It’s a clean way to add those extra circuits without piecing together multiple adapters.

Simple to Wire with Clearly Marked Pins: Labeled Socket Design

No guessing which wire goes where. Once you pull the rubber plug on the back of the socket, every terminal position is labeled by function. You can match each pin quickly and know exactly which one handles power, ground, brakes, or lights. That labeling keeps the wiring straightforward and helps avoid mistakes during install.

Straightforward Install for Solid Connection: Plug-Only Vehicle-End Setup

This plug mounts directly at the vehicle end and pairs with your existing tow wiring or coiled cable. It’s a plug-only design that keeps things tidy and secure without adding extra cable bulk. Most folks just attach it in place of their old connector and are ready to tow again within minutes.

Built for Reliable Towing Power: Standard 12-Volt and Ground Orientation

The center pin typically handles the 12-volt accessory circuit, while the ground sits at the 1 o’clock position when viewed from the front of the connector. That standard layout makes it easy to match up with typical 6-way trailer wiring and keeps your power feed consistent every time you hook up.

Video Transcript for Blue Ox Wiring - Trailer Connectors - BX294-0902 Review

Speaker 1: Today we're going to take a look at the blue ox six pole round pin trailer wiring socket for the vehicle end. This will allow you to establish a nice secure connection between your trailer and your towing vehicle with the six pole round pin wiring socket. It is a hard plastic six pole socket that will install in the rear of your two vehicle, and connects your trailer to your towing vehicle. Or, this part can also be used in the front of your vehicle that's being flat towed. Does have the concealed terminals here for durability. Pull off the rubber boot and you can see where your wire connections are.

Slide your boot over the wire, make your connections and then just slide this up to protect it. Also has a nice spring loaded lid on here, which will help keep dust and moisture out of the terminals on the front here. It is a two hole mounting style. The distance between those mounting holes center to center is two and 7/8 inches. But that should do it for the review on the blue ox six pole round pin trailer wiring socket for the vehicle end..

"A" for the product and A+ for etrailer's instructional videos. Makes installation a cinch!
by:
Blue Ox vehicle end connector and using a Blue Ox umbilical cord from RV to vehicle./ Solid connection. The connector I had was not a good fit. This Blue Ox connector is great.
by:
Replaced old, corroded, Blue OX connector. This was form, fit, and function. No complaints.
by:
I only replaced an existing Blue Ox 6-Pole, Round Pin Wiring Socket BX 294-0902 on my Chevy Equinox that was installed by a dealer and got broken. When I took the old one off, I noticed that the contacts got all rusty, so I decided to seal the end of the boot of the new socket with silicone to prevent any moisture getting into it. Installation was very simple, the socket inexpensive and the shipping fast with nice tracking.
Thank you very much

by:
This wiring socket was exactly what I needed to set up lighting for our new tow car. The 6 pole allowed me to to use pins for additional purposes like brake monitoring.
by:
Nice for hooking up your tow vehicle. Replaced the 4 pole with this . It locks the extension in.
by:
I have had problems with etrailer deliveries in the past but not with this one.
Everything went as scheduled.
Thanks to Joshua...
Excellent job!!
by:
This item is a must have addition to the Blue Ox Tow Bar Wiring Kit. It attaches nicely to the Blue Ox base plate on my vehicle and allows for an easy electrical connection between the "toad" and the motor home, using the Roadmaster 7-Wire to 6-Wire Flexo-Coil Kit.
Highly recommend this necessary piece.

Im still loving it

by:
All items arrived in a timely manner. All parts received, in process of installing. So, far all things are good to go.
by:
Working out great. Thank you

Works great!

Bought this as an exact replacement for my original that was damaged. Installation was straight forward and took just a few minutes. Blue Ox products are sturdy, well-made, and worth every penny. BTW, eTrailer.com was the ONLY place I could find this particular part (including the Blue Ox web site). From my limited purchases at eTrailer.com I can say that they have absolutely the best user interface for reviewing, comparing, and learning about any given product, and their prices generally the lowest. Especially helpful are their product videos. This site is the go-to place for anything to do with fun stuff.

All is still honky dory after a year. I guess its about time I order some more stuff from etrailer.com.

by:
Excellent service and very fast delivery
by:
So far so good after a year and lots of use. This was a replacement for an identical part that had one of the mounting ears break off. Connecting to the existing harness was difficult because the existing wires were barely long enough to reach the installed position with no slack to allow convenient positioning of the socket while each wire was connected.

Just in the last month one of the two mounting tabs broke. This happens when we hit a particularly large rough bump or pothole. This time it was very cold - probably in the teens- which makes plastic parts even easier to break.

by:
Purchased the flat tow bar, connector and wiring harness for towing my CRV behind my RV. . The phone support was great, information was accurate. All parts were received timely. The etrailer YouTube videos were excellent f.or step by step instructions. I saved a bundle doing the installation myself.
by:
The product was easy to install and has worked perfectly to provide lighting to my towed Jeep Patriot and power to an RVi Towed Battery Charger which keeps my Jeep battery charged while towing.
by:
Received the products exactly as ordered. One to replace the original. ( which still was functional) and a backup for the tool box for personal future use or to help another person in our camping group. After 5 yrs and a lot of use.the plastic eyelets for the for the attachment bolt fractured. Appreciated e-trailer’s communication regarding the order received and shipping notice which included a postal tracking number.
I am pleased with the price, product and service provided I now have a go to supplier for any future needs. Install required a small blade screw driver to attach the wiring and was straight forward and easy. As well as a Socket/ratchet to remove and install. Done in minutes. Thank You!
by:
Bought this to replace an existing Blue-Ox 6-pin that had water infusion and subsequent rusted wiring connections. Good price and quick ship. On this replacement I drilled a 3/16" hole on the bottom of the rubber boot to allow any water that gets inside to drain.
by:
I ordered and received a Blue Ox 6-pole, round pin wiring socket to replace one that was broken. The socket was quickly and courteously shipped, well packaged, and received in great condition. This socket is used to connect the controls in my mororhome to the braking system in my Honda CR-V. This socket makes a secure, positively connect link between my motorhome and the towed vehicle.
by:
Ordered baseplate, wiring kit and connector for my new jeep wrangler sport. All the products were of excellent quality. Installation instructions were ok, but not update for my newer 2021 model. What was provided in conjunction with the etrailer [online] videos did cover it. Staff was extremely knowledgeable on the products needed and very pleasant to deal with. Would definitely recommend using them.
by:
Great product and worked perfectly. I have used etrailer for many products and it is unbeatable for service and price.

Still works great after one year!

by:
The product is the right replacement for the one that corroded on my truck. However because the shipment was by USPS it took too long to get it. Had a trip coming up and need to have my lights working properly. So had to go to local Tractor Supply and get an after market connector. I will hold this for a future issue.
by:
this item is better fitted upside down so you can see what you are doing when attaching the trailer plug. The spring loaded cover is very strong and keeps flicking closed when you are trying to position the trailer plug. Also as this is attached so low down on the vehicle front six or eight inches off the ground the view of the connection is blocked by the spring loaded flap so you have to work by "feel"
by:
Fits like a glove on my roadmaster base plate on my 2020 chevy equinox. Very high quality construction. Strong spring makes a tight seal to keep water out of wiring.
by:
Needed this product to get my lights working on my tow vehicle. I was able to get a OEM Blue Ox part from etrailer for under $10 to correct my problem. etrailer quickly shipped the part, and followed up to ensure I was satisfied. Took me 20 minutes to install. Would have been $100 charge at the RV shop.

  • Looking For 6-Round Plug To Replace Pollak Receptacle With Loose Connection
    Hello Emory, thanks for reaching out. Yes I'm not a huge fan of the Pollak plastic plugs either. We do have a replacement 6-round plug from Blue Ox part # BX294-0902 which should be a better match for your Blue Ox cord. I've had good luck with these in the past. Or if you don't want another plastic plug, we do have a die-cast zinc plug from Pollak part # PK11609. These metal plugs are typically an upgrade from the standard plastic plugs and make for a nice, secure connection. I understand...

  • Connector Needed to Attach 6-Pole Plug Into Vehicle Tow Bar Wiring for 2017 Ford F-150
    From the picture that you sent me and the way you described your setup it looks like you already have a connector connected to your RV much like the Hopkins Heavy-Duty Trailer Coiled Extension # HM47055. If this is the case then what I recommend doing is cutting the 4-Way flat connector off of the harness on your 2017 Ford F-150 and installing the Blue Ox 6-Pole, Round Pin, Trailer Wiring Socket # BX294-0902 instead. It is a very easy installation which you can check out in the attached...

  • Which Pins of 6-Way Connector are 12 Volt and Which are Ground
    On a 6-way like the # BX294-0902 that you referenced the center pin is typically the 12 volt accessory circuit and then the ground is the one in the 1:00 position if you are looking into the female connector's opening.

  • How To Replace the 4-Pole On a Blue Ox Base Plate Kit with a 6-Pole
    The 6-Way Super Sealed Connector with Cable part # 50-86-007 has mounting holes spaced 2-7/8" to 3-3/8" apart. That said, if you have the Blue Ox Base Plate Kit part # BX2628 on your 2013 Ford Edge then you will want to use the Blue Ox 6-Pole, Round Pin, Trailer Wiring Socket part # BX294-0902 which is designed exactly for this base plate kit and will be a direct replacement. Then, in order to run the charge line to the battery you can use the Battery Charge Line Kit for Towed Vehicles...
