wires on front turn signal bulb holders

[VR6 vanagon]

I just got my new smoked front turn signals from Van Cafe. When I opened them up I discovered that they are wired different than the stock configuration.
There is 3 wires on each bulb holder, the brown is the ground I am thinking, how do I tell what the other 2 wires are for? I am thinking 1 wire powers the city light and 1 powers the turn signal. Any way to tell what one is what?
Both of my bulb holders were very corroded and neither one worked, so I couldn't just unplug wires to see what light went out.

middle one on both lights is the ground (rule of thumb on German cars..."if it's brown, tie it down"). On the other two, one is the running lights, one is the turn indicator. On mine the colors ran (from top to bottom)

Right side: Red stripe, brown, Green stripe

Left side: White stripe, brown, black (or grey, can't remember) stripe

If you get either of the two top or bottom wires reveresed, your van WILL explode....J/K
All that will happen is your turn indicator will blink real fast, just pull the light off and reverse the top and bottom wires on it.

I have used the brown as the ground, but the only thing I am getting is my light coming on all the time. I can't get it to blink.

use the bulb as a guide. connect the bulb to the socket with the running lights on. if the brighter filament is lit (as the running light) then you have it backwards, switch the two outside wires.

You can't go wrong this way. The bulb has two filaments, one brighter than the other. Check and switch if needed.

As an added thought I have seen light housings melt because the brighter filament (signal) was constantly lit as a running light.
