There are two different headlight switches for Vanagon:
Early: # 251-941-531M (1980-1990)
Late: # 251-941-531T (1989-1991)
From the front they look and function identically. However, they are slightly but significantly different on the back. The early style switch has only 8 pins, while the late style switch has 10 pins.
The 10 pin option is no longer available from VW and we are only offering the early style, 8 pin switch.
