I just installed my new turn signal switch into my bug. It is the '71 turn signal w/ the brass horn contacts and the tail of wires (8 wires to be exact). This is a one-year-only model.
What are the two grey wires (grey & grey/black) used for? Using my multimeter I confirmed that these two wires are connected together when the switch is in either the left or the right position. So they can be used to indicate when the turn signal is in use, but do not give a direction.
I'm pretty sure the two grey wires (grey & grey/black) were incorrectly wired by the PO. The grey wire was connected to the grey wire from the ignition switch which should be used for the door buzzer. The other wire (grey/black) was connected to fuse #1 (non-fused side). Now this seems wrong to me, so I disconnected the two wires from the turn signal and taped them up. Such a setup would ground the #1 fuse when ever the engine was off and the key was in the ignition. It's a good thing the old switch was defective, or the ignition switch grey wire is broken.
All the functions of the turn signal work fine w/o the two grey wires... so what are the grey wires for?
