Features to know about
Simple Way to Add Trailer Lights: 4-Pole Flat Connection
If you just need the basics—running lights, turn signals, and brake lights—this 4-pole flat connector gets it done. The Curt Wiring Harness with 4-Pole Flat Trailer Connector gives you the standard hookup found on most small trailers, so you can tow safely with the correct light signals every time.
Straightforward Install for DIY Setups: Splice-In Plug and Lead Design
This harness uses a splice-in, plug-and-lead design made for simple wiring jobs. You connect it directly to your vehicle’s existing wires without worrying about special modules or converters. The setup is clear and direct, which makes it ideal for quick installs or replacing worn factory plugs.
Clean Vehicle-End Connection: Ready to Plug Into Your Trailer
Once installed, the vehicle-end connector provides a solid 4-flat plug that mates cleanly with a standard trailer wiring outlet. The plug end goes on your vehicle, and the trailer’s wiring hooks right in—no adapters or guesswork needed.
Gives You Enough Reach: 48" Harness Length
With 48" of harness length, you get enough wire to route where it needs to go without stretching or pulling. That extra bit of reach helps keep your wiring tidy and protected from moving parts or weather exposure.

I purchased 4 of these connector assemblies in order to fabricate adapter/extensions for trailer connectors on commercial tow trucks. The quality of the components seems appropriate for the price point, and sufficient for the intermittent use they will see. The 48" length was perfect for my application.

I have a 2023 Honda CR-V Hybrid Sport. This is the front wheel drive model. I thought that I would have to remove the back bumper cover but I didn't. Once the bottom cover was removed, I removed the two push pins at the far corners of the bumper cover. That allowed me to push the lower part out far enough to get the hitch installed. I installed it by myself and after I figured out that it would fit, it took about 2 hours to install. Made about a 4"X4" cut in the middle bottom of the bumper cover and notched out the bottom cover and it was perfect. All that shows is the receiver itself. Couldn't be happier with the hitch. The hardest part of the install is prying off the two rubber exhaust hangers. A little WD40 helped. They were much easier to reinstall. I do have to say that the fit is tight to the hybrid battery pan that sticks out the bottom. I don't think there was much more than an eighth of an inch clearance on either side.

See what our Experts say about this CURT Custom Fit Vehicle Wiring
- Recommended 4 Pole Wiring Harness for a 2005 Chevrolet Silverado 1500Steve, we do have a T-one harness for your Silverado # 118384 but it's only going to work with the factory 7-way. From what I can see there is no plug and play option for your Silverado, so realistically your only option would be to use a universal harness # C47NR. You're also going to need the Curt 2 to 3 Wire Light Converter # C56196 to convert your 2 wire system to a 3 wire.
view full answer... - Does the Hybrid and Non-Hybrid Hyundai Santa Fe Use the Same Trailer HitchAaron yes, the Hybrid and Non-Hybrid Hyundai Santa Fe's can use the same hitch. As far as wiring goes, I'm not seeing anything that is custom so you'd be limited to a universal harness # C47NR.
view full answer... - Recommended 7-Way for a 2006 Tiffin Allegra Bay on a Workhorse W22 ChassisHey Kurt. It sounds like you need an OEM wiring harness that is designed specifically for a Workhorse W22 chassis. That's not something we carry and I don't know if one would still be available. My only solution to adding a 7-Way connector would be to install the Universal Installation Kit for Trailer Brake Controller item # ETBC7. This is not a custom fit option and would also require you to install a 4-way connector like item # C47NR that would splice into your tail light harness. ...
view full answer... - Can A 4-Pole Wire Harness Be Spliced Into A Truck's 7-Way Hey James, You can splice into the 7-way wiring and install a 4-pole wire harness like the Curt # C47NR but if the wires you're splicing into aren't functioning the 4-pole won't work either. If the 7-way isn't working you'll want to check your trailer specific fuses to see if they're blown and then trace the wiring looking for any damage or loose connections.
view full answer... - Trailer Hitch and Wiring for a 1972 Pontiac Firebird Michael, there are things available for your 72' Firebird but none of it is custom. For a trailer hitch you can use the Adjustable Width Trailer Hitch Receiver for RVs # C13702 for frames that are 18" to 51", or the Adjustable Width Trailer Hitch Receiver for RVs # 13703 for frames that are 22" to 72" wide. For wiring, you can use the Curt Wiring Harness with 4-Pole Flat Trailer Connector # C47NR. Finally for a ball mount you can use the Draw-Tite Ball Mount w/ 2" Ball for 2" Hitches...

This kit will utilize an existing 4 pole connector, so if you don't have one you can add one with # C47NR.
view full answer... - Can You Replace Your 5th Wheel Pin Box With A Higher Capacity One To Triple Tow A Boat Trailer Manufacturers recommend only using 80-85% of a pin box's capacity so you would definitely be putting too much of a strain on the pin box if you were to exceed the capacity and would most likely have something fail. Swapping pin boxes is as simple as unbolting the old one and popping in the new one, but there are limitations due to the strength of the trailer's frame. Manufacturer's don't really want you to upgrade because the higher capacity pin boxes weigh more and you're throwing off...
view full answer... - Trailer Wire Harness Needed For A Trike And Bushtec Motorcycle Trailer If you're wanting wiring to go from your trike to the trailer then you can use a harness like the Curt Wiring Harness with 4-Pole Flat Trailer Connector - Vehicle End # C47NR and splice it into your tail light wiring. If you're wanting wiring for the trailer then you can use the Optronics 25' 4-Way Trailer Wiring Harness - Wishbone Style # A25W2GWB.
view full answer... - Should The Ground For A 4-Pole Trailer Wire Harness Be Ran To The Frame Of The TrailerYou would be able to splice into the ground for the tail lights but you should really just run the ground to the frame of the trailer instead. It's the best way to ensure that you have a proper ground and won't have problems later on. You'll want to make sure you get a 'vehicle end' 4-pole connector like part # C47NR and some heat shrink butt connectors # DW05744-10 for a waterproof connection.

For the hitch you'd just need to measure the distance from the inside of the frame beams to determine which hitch would fit. The Curt Adjustable Trailer Hitch Receiver # C13701 you were looking at fits a frame width of 18" - 51" and has a 5,000lb capacity. if...
view full answer... - Is The Demco Kar Kaddy X Tow Dolly Capable Of Towing A 2014 Lexus RX350Yes, both the curb weight and wheel spacing of your 2014 Lexus RX350 fall under the capacities of the Demco Kar Kaddy X Tow Dolly w/ Disc Brakes # DM9713093. This tow dolly comes with everything you need to strap down and tow your Lexus. Your motorhome will just need a 4-pole flat connector in order to properly display your brake and turn signals through the LED lights on the fenders. If you don't have a 4-pole connector then you can use a universal one like the Curt # C47NR and wire...
view full answer... - What Plugs Into Standard Flat Trailer Wiring Outlet on a CarHey Savas, you probably have a standard 4 pole harness which would normally be used with something like the Curt Wiring Harness with 4-Pole Flat Trailer Connector # C47NR. The wire end would normally already be wired into the trailer and the plug end would get plugged into your vehicle. If you have something different let me know down below in the comments and we'll get to the bottom of this.
view full answer... - Is There An Adapter To Use The Custer Tow Bar Light And Still Connect The Tow Dolly Lights There currently isn't an adapter to allow you to use both the Custer Wireless LED Tow Bar Light # LIW-LDTL-7B and lights on the tow dolly. That being said if the tow dolly has a 4-pole connector you could just splice in a separate 4-pole connector # C47NR to you motorhome's tail lights to get the signal to send back to your tow dolly.
