Quickly and easily install a 4-way trailer connector on your Ford Maverick with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

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 assemblies 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.
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.
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.

Easy to install in 2024 Maverick. Plug and play with existing harness and just need to run a 12v hot write to the unit.
Works as advertised … install went well, instructions were good

So far so good ... zero problems.
Good overall product. Hitch install went well. Instructions were good and the video on the website was also helpful. The hitch trailer wiring was a pain, the instructions were not great but the video on the website was good. The install time was quick regarding the hitch but the wiring took much longer than anticipated, hours.
The connector plugs have alignment guides that don't fit to the 2025 maverick taillight connectors. Had to shave them off for them to be able to connect together. You have to be creative when routing the wiring. I lowered the spare tire and removed the box on the right side under the taillight. The wire to the engine compartment wasn't fun either. The install took about 3 hours with no help.
Easy install for 2024 Maverick hybrid
Combined with e-Trailers installation videos this harness was the perfect choice for my Ford Maverick. Installation was straight forward and all the necessary pieces were included.
Lauren was on top of every question I had from the beginning to the door, Great Customer Service.
Product was exactly what I needed however I no longer needed it because I sold the vehicle it was for. Thanks though for the excellent service.
This is a great product, worked out excellent. Contrary to the instructions I connected it to the vehicle flexbed 12 volt source and that really simplified installation. With some purchased flexbed connectors the final assembly was all plug and play.
Installed yesterday. Only issue with the install on our 22 Maverick Lariat was how to route the power lead to the battery in the engine compartment. Finally removed drivers side fasteners holding the fiber mat that encloses the entire underside and routed the wire behind the tail light, above the mat and then fished it into the engine compartment from behind the front wheel well. Everything seems to work fine so far, but a more complex install than anticipated due to fiber mat. Love the fact that no wires had to be cut/spliced and harness is completely isolated from vehicle electrical system.

Directions need to be improved.
Ford installed my shell but could not wire third brake light. It has a 4pin but if I used that, it turned off the blindspot sensors. I found this at E-Trailer. It worked perfectly. I didn't need the trailer parts and just used the jumper/pigtails.
Service was very fast and informative. Would use etrailer anytime I needed to.
Easy to install
Would recommend
Using for towing a small trailer

A year later, and no issues with the wiring harness after about 10k towing and another 10k driving
