I've got a couple questions about the front turn signals on the 3rd gen....

1. Which wire at the bulb is the positive 12 volt wire?
2. Do the turn signals blink because a relay is supplying the bulb 12 volts, then zero, 12 volts, then zero, etc?

I haven't decided about installing the VW sidemarkers yet, but I found an alternative today that I might go with. Just want to clear up these power questions before starting the install.

Thanks guys. Later.

Not sure but a Meter or test light will help for sure. Most times its a relay that is used to make the voltages go +12V and -12V

usually the ground wire is black or black and another color ( black with a white stripe,etc)

This will explain everything:

But it is NOT a relay. It's a simple unit called a Thermal flasher. The article explains everything clearly.
