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?...

Might be useful to note that tail lights and running lights in this case, are the very same connection.
