Getting your trailer lights working shouldn’t mean tearing into your van’s wiring. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part #C55338, plugs right into the factory connectors behind the tail lights. No splicing, soldering, or guesswork—just plug it in and it’s ready to go.
The harness connects directly behind the tail lights, keeping the install clean and straightforward. Once the trim panels are removed, the connectors snap together with the factory plugs. It’s a direct fit that saves time and gets your trailer wiring ready fast.
The built-in 4-pole flat connector provides everything needed for standard trailer lighting—running lights, turn signals, and brake lights. When it’s not in use, the connector can rest neatly inside the cargo area to stay protected from dirt and weather.
If you decide to tow a trailer with brakes later on, this harness is a solid starting point. It can be paired with a universal wiring kit for a trailer brake controller when you’re ready to expand your setup, making it easy to step up from basic lighting to full towing capability.

I was surprised to find a ready made, plug-in, trailer wiring harness for my 1992 Chevrolet G20 van. I Installed it and it is working fine. It saved me a lot of time and headache of tracing down individual wires, splicing and such. Price was very reasonable. Thanks.
Very nice wiring harness that plugged in directly to my taillight harness. No cutting/splicing needed. Arrived ahead of schedule which is incredible because I live in Alaska, that never happens for us. Will definitely do business again with etrailer.com
Hitch installed with little trouble!
Pretty straight forward wiring. I didn’t know wiring and was able to put this in fairly easy. Comes with a little instruction booklet to prevent confusion on install.
