CURT 55513 Vehicle-Side Custom 4-Pin Trailer Wiring Harness
Manufactured by: Curt
If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation.
Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Toyota Tacoma, T100 and Hilux (to verify your vehicle compatibility, see application info) It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use.
You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite However, turning that picture into a reality takes more than just daydreaming It takes a solid connection and the right amount of power.

CURT 57672 Dual-Output 4-Way Flat Vehicle-Side to 7-Way RV Blade Trailer Wiring Adapter
Manufactured by: Curt
There are several different types of connectors used to supply power from a tow vehicle's electrical system to a trailer's wiring system Some trailers only need the bare essentials -- running lights, brake lights and turn signals -- while others require a connection for reverse lights, electric brakes and auxiliary power With connectors ranging from simple to complex, it may be the case that the connection between your vehicle and your trailer is not a perfect match.
For example, your truck may be equipped with a 6-way round socket, but your trailer may have a 4-way flat plug For this very common problem, CURT offers a quick and simple solution in the form of an electrical adapter An adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and vehicle socket.

Some manual wiring is required This multipurpose socket also comes with dust covers, a mounting bracket and all necessary mounting hardware for a complete installation All CURT wiring and electrical products come with a one-year limited warranty to give you the assurance you need to tow with confidence..
Features:
- Adapts a 4-way flat socket to fit 4-way flat and 7-way RV blade trailer plugs
