Yes, the Curt 55377 is designed for Chevrolet Express and GMC Savana SUVs, mini and full-sized vans. The harness includes two ends with different coloured wires (yellow and green) to connect to the taillight wiring on both sides of the vehicle.
The Curt 55377 is a custom wiring harness designed to provide trailer lighting connections for Chevrolet Express and GMC Savana vehicles. It includes a converter box that connects to the vehicle's existing taillight wiring and provides a 4-flat connector for trailer use.
The package includes a custom wiring harness with yellow and green wire ends, a black converter box, a white ground wire with ring terminal, a provided screw for grounding, double-sided tape for mounting the converter box, a 4-flat dust cover, and cable ties for securing loose wires.
You will need a drill with a 3/32" drill bit (if a suitable existing grounding point is not available), a screwdriver, and a test light or properly wired trailer for testing after installation. The manual does not specify additional tools required.
Open the rear doors and remove the rear scuff panel. Then remove the interior trim panels directly behind the taillights on both sides of the vehicle to locate the vehicle taillight wiring harness connectors. The connectors will be similar in appearance to those on the custom wiring harness.
Separate the vehicle's taillight connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors on the driver side. Make sure the connectors are fully inserted with locking tabs in place. Repeat on the passenger side using the harness end with the green wire.
Drilling is required only if a suitable existing grounding point is not available near the taillight connector. If needed, drill a 3/32" pilot hole in an area free of rust, dirt and paint. The manual warns to check for hidden items behind or under any surface before drilling to avoid damage and personal injury.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole in an area free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
Locate a flat spot inside the vehicle near the taillight. Adhere the black converter box using the provided double-sided tape. The manual does not specify cure time or adhesive strength requirements.
When in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Test for proper function by using a test light or connecting a properly wired trailer. The manual states that all steps must be followed to ensure the wiring harness will function properly, but does not provide detailed testing procedures.
The Curt 55377 is rated for 3.0 amps per side for signal circuits and 5.0 amps total for tail and running circuits. Do not exceed these ratings or your vehicle's tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.

Yes, you must open the rear doors and remove the rear scuff panel to access the interior trim panels behind the taillights where the vehicle's taillight wiring connectors are located.
Install the provided 4-flat dust cover to help prevent corrosion. The manual does not specify when or how to apply it, but it should be installed as part of the final step after all other components are in place.
Yes, the Curt 55377 is designed for Chevrolet Express and GMC Savana SUVs, mini and full-sized vans.

Signal circuits: 3.0 amps per side. Tail and running circuits: 5.0 amps total. Do not exceed these ratings or your vehicle's tow lamp load rating, whichever is lower.
