Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light trim covers to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

  • 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...

  • 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...

    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...

    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 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...
