What the hell would you want 2 indicators for?
I'm assuming you want to make them look like the R32 headlights?..
The easiest option would be to make sure you have the headlights with the front fogs in.
Then just replace the fog lens and bulb with the indicator ones.
Just splice onto the indicator wire in the headlight unit and it should blink with the other bulb.
That's what I'd try anyway.
But the only problem afterwards is the fact that R32's were the only MK4's that came with projector units.
So you'd have to modify a projector housing from some other lights onto the unit. That's if you want them to look like R32 headlights.
Or the other option is just buy some.
