Expert Answers about Kawasaki Vulcan

• Replacement Powered 4-Wire Trailer Harness for 2010 Kawasaki Vulcan
• It sounds like you're looking for a wiring kit like the 4-Pole Trailer Connector and Installation Kit # C59496. This comes with the 6-wire input and then converts to the 4-wire output like what you mentioned. The black wire is for 12V battery power and then the red wire is that brake wire. You can just cut and splice this harness in to where your current connections are so you don't have multiple spliced connections.
