  • Cut the C9 wire (buzzer)
  • (Dimmer)-Connect a potentiometer between pins b20 and b22 on the cluster. The wrx harness does not have any connectors on these pins so all I did was shove the ends of the wires into the empty slots and secured it.

    With the headlights turned on you lower the brightness of the cluster until it makes a sudden drop in light (this is the night setting)....when you turn the headlights off the cluster goes back to the brightest setting. This is the potentiometer I used
why buy a potentiometer from radio shack when you dont need one? why wouldnt you just use the factory controls on the steering colum?
