Features to know about

Installs Without Cutting or Splicing: Plug-In Harness

Wiring a trailer isn’t always simple, but this Curt T-Connector makes it easy. It uses a plug-in design that connects directly to the vehicle’s factory wiring—no cutting, no splicing, no guesswork. Just plug it in and you’ve got a clean, dependable 4-flat connection ready for towing.

Keeps the Factory Look: Hidden Plug-and-Lead Setup

You don’t have to settle for loose or messy wiring hanging below the bumper. The hidden plug-and-lead setup keeps everything tucked away until you need it. When you’re done towing, the wiring stores out of sight for a factory-clean look.

Ready for Basic Trailer Lighting: 4-Flat Connector

The built-in 4-flat connector gives you what most trailers need—running lights, turn signals, and brake lights. It’s the standard connection for small to mid-size trailers, so you can hook up and go without extra adapters or converters.

Simple Addition for Vehicles Without a Tow Package

Even if your vehicle didn’t come with a tow package, this harness has you covered. It’s designed to plug right into existing points in the wiring system so you can add trailer lighting capability without modifying anything else.

WONDERFUL PRODUCTS



by:

Easy install like the plug and play



by:

Follow the instructions, pretty easy installation, routing of the plug wiring was a bit tight, that part was a bit challenging.



by:

This worked out very well but instead of wiring the 12 volt wire all the way to the battery I just spliced into the 12 volt accessory plug in the cargo area



by:

Works as advertised. I haven't had any trouble with it. It wasn't overly difficult to install. I'd recommend it.



by:

Good instructions. Worked as it should



by:

It works as expected. I recommend watching the online etrailer installation video. No surprises... Everything is exactly as described. I also recommend raising your vehicle (especially the rear end) during install to make things easier. I decided to do this late in the process and really wish that I had done it from the start.

  • Recommended Hitch for a 2023 Jeep Compass
    Yes, there is a hitch available for your 2023 Jeep Compass. I recommend the etrailer Hitch item # e48AR. This hitch is custom fit and bolts to your Jeep with included hardware. I really like this hitch because the crosstube is hidden behind the rear bumper cover. This leaves only the 2" receiver visible which not only looks better it also helps with ground clearance. I have attached a picture below so you can see what this hitch looks like once installed. If you are planning on towing...

  • Recommended Hitch for a 2022 Jeep Compass
    To add a hitch to your 2022 Jeep Compass, I recommend the etrailer Hitch item # e48AR. This hitch is custom fit and bolts to your Jeep with included hardware. I really like this hitch because the crosstube mounts behind your rear bumper cover leaving only the 2" receiver visible. Since you are planning on towing you will also need a wiring harness item # C66BR and a ball mount kit item # C45534. I also recommend using the No-Drill Mount Bracket item # 18136 and the item # C42CR to secure...

  • Recommended Hitch for a 2023 Jeep Compass
    I would be happy to! To add a hitch to your 2023 Jeep Compass, I recommend the etrailer item # e48AR. This hitch is custom fit and bolts to your Jeep with included hardware. I really like this hitch because the crosstube mounts behind your rear bumper leaving only the 2" receiver exposed. This not only looks better but helps with ground clearance. The etrailer Hitch item # e48AR is a class III hitch with a 2" receiver. It has a 4,000 lbs towing capacity and a 600 lbs maximum tongue weight....

  • Will etrailer Trailer Hitch Receiver Fit 2023 Jeep Compass Trailhawk
    The etrailer Trailer Hitch Receiver # e48AR fits all models of the 2023 Jeep Compass. This includes the Trailhawk with the dual exhaust. For wiring you can use the Curt # C66BR. This wiring harness plugs into the connection points behind the tail lights. Once installed, your friend will have a 4-way to power a trailer's signal lights. I see you also looked at the # ETBC7. If the goal is to add a 7-way then this kit is the right choice. One way or another you have to start by adding the...

  • Does The etrailer Trailer Hitch Receiver Require Drilling To Install on a 2023 Jeep Compass?
    While you will not have to drill mounting holes for the etrailer Trailer Hitch Receiver # e48AR on your 2023 Jeep Compass, you may have to increase the size of an access hole to insert the square hole spacers inside your frame. You will also need to trim a small portion of your rear fascia for the receiver tube. I recommend installing the Curt T-Connector Vehicle Wiring Harness # C66BR when you install the receiver. This will give you a 4-way flat connector. This connector is the most...

  • Will Draw-Tite 76144 Trailer Hitch Receiver Fit 2022 Jeep Compass Latitude LUX
    Yes, the Draw-Tite Max-Frame Trailer Hitch Receiver # 76144 will fit your 2022 Jeep Compass Latitude LUX. However, I recommend the etrailer Trailer Hitch Receiver # e48AR instead. The Draw-Tite has a visible cross tube so you're going to see the entire hitch hanging down below the rear bumper. The etrailer hitch has a concealed cross tube which means only the receiver will be visible. This gives it a nice clean look while also improving clearance. The etrailer hitch also has a matte black...
