The harness has the 4-flat plug that is common on most trailers, so yo should be set there. If you have the receiver, you are getting warmer. What you may not have is the drawbar, the male piece with the ball on the end that the trailer actually attaches to. You could by one from the LR store, but I suspect that the U-haul place may be able to rent with the trailer, or sell @ a reasonable rate.
