5 PIN ROUND
5 Pin Round plugs are becoming less common these days as they are not compatible with the 7 Pin Round. The wiring is similar to a 7 Pin Round and you often see people "daisy chain" their indicators into pins 1 and 4 to suit. I wouldn't recommend using this set up as it is becoming obsolete.
