To wire a trailer for a 1979 Dodge B200 van, you'll typically need to connect the trailer's wiring harness to the van's tail light wiring. The basic color codes are: brown for tail lights, yellow for left turn signals, green for right turn signals, and white for ground. It's important to ensure that the connections are secure and insulated to prevent short circuits. Additionally, using a trailer wiring harness adapter can simplify the installation and ensure compatibility with your van's electrical system.

Secure the connection and check that the trailer lights function properly before towing. If necessary, consult the vehicle’s manual for specific wiring diagrams and troubleshooting.

You have a grounding problem at the trailer. The white wire is the ground on trailer wiring. The taillights are brown, the signals and stops are yellow and green. Sometimes the white wire will loose its continuity with the truck, causing the lights to black out. It could also be a wiring issue with the trailer itself, but most likely its the ground giving you feedback and causing the blackout. run a wire from the ground contact on your plug back to a spot on the tongue and secure the end of the wire to the trailer at that point. Do not rely on the contact of the trailer with the ball hitch to establish a ground.
