You can go to any parts house or Wally World and find the the necessary connector... the wire colors are standard and should be the same to identify the various circuits (L & R turn, running lights, return ground). If they aren't, then you need some kind of circuit tester to I.D. the wires, whether it's just a 12 volt bulb or a voltmeter. After you have the wires identified, cut the old connector, strip the ends, and splice the wires. Wire nuts are easy, butt slices are okay, black electrician's tape will do. Depending on the length of the wires of your replacement connector, you will probably want to make the splice as far back as you can, both for "beauty" and more protection.
