Question:
When using one of your 4 way flat to a 6 round adapter. My trailer has a the 6 round plug, my bike has the 4 flat plug. I assuming that the extra two wires are for lights on the trailer, how do I connect them to get them to work?

You are correct that an adapter would be needed since you have a 4-flat on your bike and 6-round on your trailer. When using that adapter, # 30637, the two wires would not be for lights on your trailer. The black wire would be to connect for a 12V power source, while the blue wire connects to the output wire on a brake controller. Those wires do not need to be used and can simply be tied up.
I've attached a link to a review video on this adapter for you to take a look at.
