Download this PDF to see how to wire your motorcycle or car in such a way that it can work with EITHER a trailer with a 4-wire flat, or a 5-wire flat. This gives you the flexibility to allow you to pull and correctly illuminate your trailer lights with a flat connection, and if needed some other trailer which has a flat connector, and may not have the same number of connector pins.

NOTE: Installing A Trailer Hitch And Your Factory Warranty. There has been and continues to be “harassment” from dealers telling you, the customer and owner, that installing a trailer hitch will “void” your warranty. THIS IS NOT TRUE! In 1975 the federal government passed a set of laws called the Magnuson-Moss Warranty Act (please look it up on the internet, and then tell your dealer to do the same). In short, it states that your warranty cannot be voided or canceled for using a non O.E.M. part or accessory (like a trailer hitch). IF the manufacturer of the vehicle can prove that the use of this non O.E.M. part or accessory caused the failure of a part or parts of the vehicle then that part or parts would not be covered under your warranty but your warranty CANNOT be VOIDED or CANCELLED.
