Hi, Had a quick search but couldn't find anything... My polo rad fan switch has three connectors on it - does anyone know which 2 to use as the switch? There are 2 larger pins and one small so I'm guessing its the larger ones, but wanted to check I didn't need the small one for something else?

Cheers, James

Not 100% sure so probably talking nutsack but I have a feeling that VW do 2 speed switches in later cars.

I would test both options so you get the fastest of the 2.

Cheers,
James
