Trailor light question.

[Sailing reenactor]

I need to hook up some trailor lights, but the instructions that came with the kit don't match the kit.
It's a 4 way with a ground. The colors are 1 green, 1 yellow, and a brown and red that are connected. The wires on the lights are 1 black, 1 yellow, and 1 white. Please help as right now I am completely guessing. (And we want to go out tomorrow) According to an algebra formula I learned I have about 200 different ways to hook it up. I think I've tried about ten.
Thoughts???

Connect the red wire (ground on the adapter, VERY non-standard) to the white wire (ground on the lights).

Don't trust the trailer to ground the connector wire or light wires --- just link 'em with two extra lengths of wire and rely on the ground system in the tow vehicle to do the work.

Most common failure I've seen in the many small boat trailers I've owned is grounding -- the wire gets corroded and fails to ground, lights then fail to work.

Thorne's post is worth repeating.

Also use a test light , not a meter for trouble shooting / figuring out what wire goes to what light.

So did you get it wired or what?
