electrical help

[johnbrunt]

i have a single stalk indicator assembly which has the following functionality

up / down - left right turn
pull - dip / main beam

i have the following coloured wires connected as follows

brown / white - connected to lighting relay
brown - earth
black / white - indicator
black / green - indicator
black / white / green - indicator relay

black / grey - not connected
white - not connected
grey - not connected

my question revolves around the three unconnected wires - what are they for as by having all the other wires connected as detailed everything works as intended.

i’m not sure what year this stalk is off but it’s on the shorter indicator / ignition switch assembly - the unconnected wires aren’t part of the ignition system as again these are all wired up as they should be.

thanks in advance

I believe the newer switches have extra wires that go unused.

In some European countries cars require an extra lamp during turns. From my understanding these do not flash so are connected to a constant power source like the ignition circuit and power an extra set of lights on the L and R. I’m not certain if they are meant to light up the roadside on the turning side of the car, or just as indicators? Those three extra wires are for that system which is not used in most countries. The aftermarket turn switch assemblies include the extra wires so a single turn signal switch can be used in all countries. VW probably had two different part#s.

Just loop them up and tuck them away. If your main turn signal switch ever fails, you can make use of them as a spare turn signal switch cricuit. Just check if they are the same wire gauge. The ones I have seen are a smaller wire and may not carry the current load for two 21W bulbs. LEDs lamps in the front or rear may be needed to reduce the current load if you use these as a spare turn signal circuit.


If your turn signal switch assembly has loose wires (not in a plastic tray) and has a large brass contact(s) on the face of the switch for horn contact ring on the bottom of the steering wheel... it is a ‘71 Beetle turn signal switch. The ‘70-earlier switch did not have the brass horn contact on the switch. The ‘72-later switches were for cars that had the turn signal and wiper switches on the steering column. The wires were laid in plastic trays and used two plugs at the bottom of the steering column housing.

I think the unused wires you have are for the European market which requires the roadside parking lamps.

Ashman beat me to it.
