In a 1987 Chevy G-20 van, the trailer wiring harness typically connects to the vehicle's taillight harness. You can find the trailer brake, turn signal, and running light wires near the rear of the van, often located under the rear bumper or near the taillight assemblies. For a proper hookup, refer to the vehicle's wiring diagram to identify the correct wire colors for the specific functions. Always ensure to use a compatible trailer wiring harness for safety and functionality.

There are about 5 fuses for the trailer harness, Trailer Back up,Trailer left turn, Trailer right turn, Trailer Brake, and Trailer hazards. They are located in the underhood fuse box on the Drivers side of your motor. On my 2003 Silverado, the Trailer left/stop and Trailer right/stop fuses are located in the fuse panel just inside the driver's side door. (Not sure about the trailer brake or hazard fuses.....I wasn't having problems with those :). There is one additional fuse for the trailer harness. The 15A fuse for the trailer running lights is located in the fuse panel under the hood, next to the battery. The fuse is labeled "Trailer Park".
Go to your local parts house and purchase a Haynes Manual that is for your particular vehicle. It will contain valuable information in regard to your vehicle.
