Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Curt Replacement 7-way RV Style and 4-way Flat OEM USCAR Trailer Connector. Now, this part here will replace the OEM connector to provide a 4-way and a 7-way trailer wiring connection, and it is designed to fit the USCAR-equipped vehicles with the factory tow plugs only. Now, the 4-way flat output right here will connect your taillights, brake lights, and turn signals, and then the 7-way blade socket will do those three, and also add reverse lights, electric brakes, and auxiliary power. Now, on the caps, they do use nice rubber gaskets that'll help keep the moisture and the elements out when the cap is closed, and they are spring loaded, you can see, so that will keep them closed, keeps the connectors clean when they're not in use, and they also use pre-greased terminals for a nice reliable connection. But that should do it for the review on this Curt Replacement 7-way RV Style and 4-way Flat OEM USCAR Trailer Connector..

Well this is where the fly gets in the mix. The reason I ordered the plug and module is because this Highlander did not come with tow package and I had to start from zero. I have no way of connecting this product to the car. Is there a plug that will connect this product to the factory connector under the vehicle.

Connector is much more robust than OEM on my 2015 Sierra. Plug and play.
E-Trailer customer service is great. Price is a little steeper than competition, but I think it translates to a better product.

See what our Experts say about this CURT Trailer Wiring
- Will Curt 7-Way part # C42JR Fit 2021 Ford F-150Hey Tom, yes the Curt 7-way part # C42JR will work on your 2021 Ford F-150 as your truck has the same style of connector this was designed to fit.
view full answer... - Replacement 7-Way and 4-Way Connector for Factory 7-WaysYes, it will! The Curt Replacement OEM USCAR Trailer Connector item # C42JR is designed to replace factory 7-way connectors. The USCAR socket is what all the manufacturer's use to connect the 7-way to their vehicle's wiring harness.
view full answer... - Does Curt 7-Way/4-Way C42JR Fit 2022 Ford F250Yes, your 2022 Ford F-250 has the same USCAR style of 7-way connection that the Curt 7-way/4-way has so it would fit and work great.
view full answer... - Does Curt 7-Way part # C42JR Fit 2017 Audi Q7Hey Bill, the Curt 7-way part # C42JR does fit your 2017 Audi Q7. The Audi part number you referenced is a standard 7-way like what this part number was designed to replace.
view full answer... - Does Curt Replacement OEM USCAR Trailer Connector C42JR Fit 2004 Toyota SequoiaYes, the Curt Replacement OEM 7-way/4-way kit part # C42JR does fit the 7-way socket of your 2004 Toyota Sequoia LTD as this is designed to fit the standard 7-way connector.
view full answer... - Will the Curt Replacement OEM USCAR Trailer Connector Fit in the Same Spot as the Factory 7-Way?Thanks for the picture! Yes, it will. The old factory connector on your 2005 GMC Yukon XL Denali will pop out once you disconnect the wiring harness and you'll be able to insert the Curt Replacement OEM USCAR Trailer Connector item # C42JR.

- Can 7-Way and 4-Way of Curt # C42JR Be Used at Same TimeHey Tom, yes both the 7-way and 4-way of the part # C42JR are active at the same time. Since both doors open to the same side the connectors can both be accessed at same time as well.
view full answer... - Recommended 7-Way and 4-Way Combo Connector that Can Be Used at the Same Time Yes, it will! However, the Curt Replacement OEM USCAR Trailer Connector item # C42JR won't let you use both the 7-Way and the 4-Way at the same time. You will need to install the Multi-Tow 7-Way and 4-Way item # 30955 to use both at the same time. Both of these 7-way/4-way combos use the USCAR connector which is what all vehicle's that come with a 7-way connector from the factory use. I have linked an installation video we did to help you get the Multi-Tow 7-Way and 4-Way item # 30955 set up.
view full answer... - Correct Trailer Connector for Bumper Cutout on 2020 Toyota TacomaYes, the Curt Replacement OEM USCAR Trailer Connector part # C42JR will fit inside the rear bumper on a 2020 Toyota Tacoma. That said, in order to complete the rest of your wiring you'll need the Tekonsha OEM Replacement Vehicle Wiring Harness part # 22117. The trailer connector will need to be replaced on the Tekonsha harness with the Curt plug. This is an excellent simple plug-in setup that will allow you to tow both trailer's with a 4 and 7-way connector.
view full answer... - Replacement Trailer Connector for a 1999 Dodge Ram PickupThe Curt Replacement OEM USCAR Trailer Connector # C42JR will work if you still have the US CAR Connector on your 1999 Dodge Ram Pickup. If you're needing to connect this to a square style connector then the only option we have is the tee-in gooseneck style like the Curt # C56071.
view full answer... - Does the Curt Replacement OEM USCAR Trailer Connector Fit Pollak Replacement Mounting BracketYes, the Curt Replacement OEM USCAR Trailer Connector # C42JR (Curt Part # 57015) fits and clips into the Replacement Mounting Bracket for Hopkins 7- and 4-Pole Trailer Connector Socket # HM40978.
view full answer... - How To Attach Curt Replacement OEM USCAR Trailer Connector to 4-Way Harness on Jeep WranglerIn order to use the Curt Replacement OEM USCAR Trailer Connector part # C42JR you'll need a harness like the Tow Ready Replacement 7-Way Harness part # 20147 which will then wire onto the existing trailer harness. For example, if you have a 2019 Jeep Wrangler you'd need to use the T-One Vehicle Wiring Harness part # 118786. The trailer connector on the T-One Vehicle Wiring Harness would be removed and then attached to the Tow Ready Replacement 7-Way Harness. There will be extra wires for...
view full answer... - Replacement Trailer 4/7-Way Connector For the Factory Connector On a 2017 Chevy Silverado 1500Yes, the Curt # C42JR will fit in place of the factory Pollak # HM40975 trailer connector on your 2017 Chevrolet Silverado 1500.
view full answer... - Will The Curt Replacement OEM USCAR Trailer Connector # C42JR Fit a 2017 Ford E-450 Class C Cutaway?You may need a Tow Ready Replacement 7-Way Harness # 20147 to install the Curt Replacement OEM USCAR Trailer Connector # C42JR on your 2017 Ford E-450 cutaway under your Thor class C motorhome. You will need to check your factory 7-way to determine if it uses the quick connect or if it is hardwired in. If hardwired you will need to either cut the wiring or disassemble the wiring from the 7-way. Be sure to disconnect the batteries before cutting/splicing this wiring. Other wise if you have...
view full answer... - Loose/Bad Connection Between Trailer Connector and Vehicle 7/4-Way SocketI do have an option for you but we don't have any specific tools to clean a trailer connector. That said, if you are getting intermittent signals this can be caused by either corrosion or worn terminals. If you don't see any corrosion then it's most likely the latter and you'd be best off to just replace the connector either on the vehicle or trailer. If you can send me a photo of either I'd be able to see about getting you the correct replacements but it sounds like you might need the...
view full answer... - Will The Curt 7-Way/4-Way Connector 57015 # C42JR Allow For Both Connectors To Be Used When Towing?You will want to use the Multi-Tow 7-Way and 4-Way # 30955 to add a 4-way you can access while also using the 7-way blade connector. The Curt 57015 # C42JR does not allow for both the 7-way and 4-way doors to be opened at the same time. The Multi-Tow above will plug in the same USCAR connector the Curt would connect into. This will give you a separate 4-way which you can use for your Auxiliary Lights # C53201. If the 7-way on your tow vehicle is hard wired and does not use the USCAR connector...
view full answer... - Recommended 7 and 5-Way Trailer Connector for 2016 Toyota TacomaThe Tekonsha OEM Replacement Vehicle Wiring Harness part # 22117 which is a fit for a 2016 Toyota Tacoma does contain the reverse light signal. In order to utilize the factory bumper cutout you'll also need the Curt Replacement OEM USCAR Trailer Connector part # C42JR. In order to connect a 5-way connector, you'd just need the Optronics 7-Way Round to 5-Way Flat Trailer Connector Adapter part # A75TB. In the future when you do need a trailer brake controller, I highly recommend the Redarc...

I am afraid there is not an adapter that will connect the Curt connector to the 2022 Toyota Highlander. What I recommend is part # 37185 which will give you a 7- and 4-way connector. It will allow you to run the lights on a trailer with a 7-way connector. I can have our Customer Service team contact you if are interested in returning the Curt connector.
