How do I hook a 3 pin connector to a 4 pin?
First post here! I recently purchased a small camper and the runnig lihgts(I assume thats what it is) have a 3 pin connecter, can I just plug it into the 4 pin splitter I have or do I need an adaptor?...

I would bet that the plug has turn signal/brake lights and running lights, but no ground- at least that's what the colors are. (they did sometimes rely on the ball to ground.
You could try buying a four wire plug for the trailer, hook color to color, adding the white ground to the frame.
