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 Chevy Express and GMC Savana 1500, 2500 and 3500 (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, Curt part number 55335 is designed for GMC Savana and Chevy Express vehicles. The installation involves connecting to the vehicle's existing taillight wiring harnesses on both the driver's and passenger's sides.
Yes. You must open the rear doors and remove the rear scuff panel to access the vehicle's taillight wiring harnesses on both the driver's and passenger's sides.
Locate the vehicle's taillight wiring harness on the inside of the vehicle directly behind the driver's side taillight. Separate the vehicle's wiring harness connectors carefully, being sure not to damage the locking tabs. Insert the T-connector end with the yellow wire in-between the separated connectors.
Route the T-connector end with the green wire down to the floor and across to the passenger's side under the removed scuff panel, then up to the vehicle's taillight wiring harness on the passenger's side. Repeat the connection process on the passenger's side using the green wire, separating the connectors carefully and inserting the green wire T-connector between them.
Drilling is optional. On the driver's side, locate a suitable existing grounding point such as an existing screw with nut in the vehicle's frame. If no suitable grounding point is available, drill a 3/32" hole and secure the white wire using the eyelet and screw provided.
If you need to drill a grounding hole, drill a 3/32" hole on the driver's side near the connector. Secure the white wire using the eyelet and screw provided in the kit.
Adhere the black converter box to the frame of the vehicle using the double-sided tape provided in the kit.
The kit includes: a T-connector with yellow and green wires, a white ground wire, a black converter box, double-sided tape for securing the converter box, cable ties for securing loose parts of the T-connector, an eyelet, and a screw for the optional ground wire installation.
When in use, route the 4-flat wire to the center of the vehicle and out the rear cargo doors. When not in use, roll up the wire and store it in an out-of-the-way location in the rear cargo area.
Before drilling, verify that miscellaneous items hidden behind or under any surface will not be damaged. Drilling without checking can cause damage to hidden components and/or personal injury.
When separating the vehicle's wiring harness connectors, be sure not to damage the locking tabs. The locking tabs hold the connectors together and must remain intact for proper operation.
Yes. After connecting the T-connector, secure any loose parts of the T-connector with the cable ties provided in the kit.
GMC Savana and Chevy Express.
Drilling is optional. A 3/32" hole is only needed if no suitable existing grounding point (screw with nut) is available on the vehicle's frame.
The manual does not specify required tools. A drill may be needed if you must create a 3/32" grounding hole, and basic hand tools are likely needed to separate connectors and secure fasteners.
Yes, you must open the rear doors and remove the rear scuff panel to access the taillight wiring harnesses.
