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!

Did a great job putting a hitch in my truck
My ARE truck bed cover was off line & not closing properly. The repair was not an easy fix but they took their time & made sure the bed cover closed perfectly & I can now lock my bed securely again with my key fob! The price I was charged was very fair even though the job was time consuming! I am a fan & will definitely be back! Excellent customer service. & very friendly!
Professional sales people. Very nice
Just left this place and I was thoroughly impressed! Justin and Andrew were professional and knowledgeable. Thank you guys, I’m really happy with my new cam locker box.
This crew was run by Justin and a couple more worker. They were extremely friendly and super professional and efficient at their job. I am extremely pleased with the finished job and can’t say enough good about this product.
The staff was nice and helpful . I bought a bed cover and He showed me all of them and how they worked. When they put it on it was quick and professionally done.
I’ve bought 3 camper shells, 3 lift kits, a aftermarket bumper install, and a leveling kit from H&H. They’re a little pricier, but they do good work. No issues with any of the trucks I’ve sent to them.w
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.
If you want amazing customer service definitely go here! They were extremely helpful! Thank you!!!!
Very friendly service very helpful
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

Trevor and his team did an outstanding job delivering my new 10' by 16' aluminum shed to a very tight delivery location. The shed is outstanding and I was glad I went with Thrifty Portable Building. I highly recommend them if you are looking for a portable building.
Fast! My order was ready, and installed in less than 24hrs! (Would have been sooner but I had to wait till next day) Staff was very friendly, will definitely be back!
Luke went out his way to make sure we had enough space for the delivery for our new shed!! Thanks Luke! You're awesome!!!!!!!
Had the pool parts we needed and a lot of other things!
These guys are absolutely amazing. I went in looking for assistance with a part and installation on my suv sunvisor. Even though this is not something they normally service , they immediately welcomed me and took my vehicle back to the shop and installed the new visor and corrected the existing one ! Their customer service was top notch and I will definitely be back to get running boards installed. Their kindness just earned a new customer for life ! And not to mention the store was so nice , clean and well organized. 5 stars is not enough to say how pleasant my experience there was today!
