Turn Signal Switch - Black - 1966-67 Beetle - Karmann Ghia

The VW Turn Signal Switch wiring is a very simple circuit, even with the 66-67 Switches controlling the Headlight Relay. The designations for the wires are:

Black White Green Wire (with Blue Wire attached):
49a OR "L" Terminal on Flasher Relay

Blue Wire (from Black White Green Wire):
Turn Signal Indicator Bulb in Speedometer

Black wire with White Stripe: Power to left turn signals
Black wire with Green Stripe: Power to right turn signals
Brown wire with Jumper: Ground Terminal on Body
Brown wire with White Stripe: "S" Terminal on Headlight Relay


The current aftermarket switches have the following wires: Red/Black Wire with jumper: 49a OR "L" Terminal on Flasher Relay
Black/Red Jumper Wire: Turn Signal Indicator Bulb in Speedometer
(Cut the jumper wire off if you have a wire running from your flasher relay to the turn signal indicator bulb)
White/Red: Power to left turn signals
Yellow/Red: Power to right turn signals
Brown wire with Jumper: Ground Terminal on Body
(The ground terminal is typically at the left mounting screw ground terminal) Red: "S" Terminal on Headlight Relay
