Used to install modern halogen headlights on an old car. The device was connected as follows: pin 87 - yellow #14, pin 85 - white #18, pin 86 - black #18, pin 30 - blue #14, and pin 87a - red #14. I have the Pins changed to something more understandable for me: pin 30 red, pin 85 black, pin 86 blue and pin 87 yellow. (I didn't need pin 87a) and installed it.
