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 Ford Ranger (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 custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Yes, the CURT 55314 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Ford Ranger (Part #BKDK55314) is designed to fit the 1986-1992 Ford Ranger.
The CURT 55314 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Ford Ranger (Part #BKDK55314) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
The Curt 55314 is a T-connector adapter harness designed to integrate with your vehicle's tail light wiring. It connects between the vehicle's existing tail light harness connectors and allows you to route additional wiring to the center of the vehicle for trailer lighting or other accessories.
Yes, the Curt 55314 is designed for Ford Ranger. The manual does not specify model year range, so contact Curt Manufacturing or your retailer to confirm compatibility with your specific Ranger year and generation.
The manual does not specify required tools. Cable ties are provided for securing the harness to the vehicle crossmember. You will need basic hand tools to disconnect and reconnect the tail light harness connectors, and you may need a trim tool or small screwdriver to trim locating tabs if your vehicle has gray connectors (see step 3).
Yes, cable ties are provided with the adapter for securing the T-connector harness to the vehicle crossmember or other mounting points during installation.
The tail light wiring harness is located along the inside of the left rear frame rail. This is where you will find the connectors that match the T-connector adapter.
Carefully separate the harness connectors, being cautious not to break the locking tabs. Before disconnecting, check that the mating surfaces of the connectors are free of dirt and clean them if necessary to ensure a proper connection when you reconnect them through the T-adapter.
If your vehicle's harness connectors are gray, you must trim the locating tabs from both the male harness connector and the male end of the T-connector adapter before inserting the adapter. This is shown in the illustration on the manual. Failure to trim these tabs will prevent proper connection.
Insert the T-connector adapter between the separated harness connectors and lock it into place. Ensure that the connectors are fully inserted with the locking tabs properly seated. The adapter should fit snugly between the two harness connectors.
Route the T-connector harness to the center of the vehicle and secure it to the vehicle crossmember or other suitable mounting point using the cable ties provided. This prevents the harness from hanging loose or becoming damaged by moving parts.
Locating tabs only need to be trimmed if your vehicle's harness connectors are gray in color. If your connectors are a different color, trimming is not necessary. The manual does not specify which model years or trim levels have gray connectors.
Before beginning installation, verify that miscellaneous items hidden behind or under surfaces (such as fuel lines, brake lines, or wiring) are not present in the areas where you will be working. This prevents damage to the vehicle and personal injury. Take care not to break the locking tabs on the connectors during disconnection.
Ensure that the T-connector adapter is fully inserted between the harness connectors with the locking tabs properly seated. The harness should be securely routed to the center of the vehicle and fastened with cable ties. The manual does not provide a post-installation testing procedure; contact Curt Manufacturing for guidance on testing the electrical connection.
The Curt 55314 is designed for Ford Ranger. Confirm your specific model year with Curt Manufacturing or your retailer, as the manual does not specify year range.
The T-connector adapter harness and cable ties for securing the harness to the vehicle are included.
Only if your Ford Ranger has gray tail light connectors. In that case, trim the locating tabs from the male harness connector and the male end of the T-adapter before inserting the adapter.
The T-connector adapter connects between your vehicle's tail light harness connectors, which are located along the inside of the left rear frame rail.
Verify that no miscellaneous items (fuel lines, brake lines, wiring) are hidden behind or under surfaces where you will be working. Ensure the tail light harness connectors are clean and free of dirt.
