CURT 55774 - Custom Wiring Harnesses, N/A

See it in action

Description

A CURT custom wiring connector (sometimes called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring. Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURT's custom wiring connectors come into play. A custom wiring connector uses a single original equipment plug to plug into a special socket provided by your vehicle. Though this option is not available on every vehicle, some automotive manufacturers design their vehicles to be easily equipped for towing by supplying a socket, integrated into the vehicle's electrical system, to readily accept a custom wiring connector. With a CURT custom wiring connector, there is no need to tap into the taillight assembly because a special socket is already provided. This special custom wiring connector actually provides two connector sockets for a multipurpose option. It plugs into an OEM connector and offers a 4-way flat and 7-way RV blade connector. It comes with a mounting bracket for easy installation and is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment). CURT custom wiring connectors are designed to be long-lasting and simple to install. They come with dust covers to keep your connector clean when not in use.

    The guys at H&H went the extra mile for me, and I greatly appreciate it. Due to transmission problems in my son’s van, we needed a trailer hitch put on as soon as possible on my van so that we could go on our plans Vacation. H&H made it happen in less than 24 hours Ordering in and installing the required trailer hitch and electrical adapters. The installation was flawless, and the parts worked perfectly. Great job all the way around! I am very pleased!

I recently had a tonneau cover installed on my truck and was very pleased with the customer service that I received. The associates were very helpful, were great to work with and did an exceptionally well job with the installation. I highly recommend H & H to anyone who is considering doing any truck upgrades. Also, an extra thanks to Cary for all the assistance he provided.

I ordered retractable running boards for my Bronco, then called H&H to install. Tyler got me in the very next day. They did a great job on the install and walked me through the details when I picked the vehicle up. They are my provider of choice for any future upgrades.

The showroom was very clean and the shop area was for employees only but the only thing that was concerned about was the price of the parts and labor but the in and out time was not bad

Go to LEER Truck Accessories by H&H for your truck needs. Luis and Justin were perfect, I purchased my own running boards to get installed on my truck. Let’s just say the prices were VERY REASONABLE!!!!!!!!! My appointment was at 2:00pm and out with my truck at 2:45pm. Job well done guys. We just moved to the area and I was looking for a truck accessories company. You cannot go wrong with LEER Truck Accessories by H&H. So if you are in the area of Marietta off of Cobb Parkway stop by and check those guys out. I will definitely be back for more upgrades for sure. Thanks you have a customer for life!!!!!

I was desperate, I couldn’t open my truck topper door. I stopped there to see if they could help. WOW did they ever! Very great service, friendly & mechanically qualified to help. Had the door open & repaired in less than 15 minutes. I tried to pay & they said; “no charge”. I’m definitely going back there! Mike H
