As per title? It's a two wire IAC valve. Can I just plug this into the fiddle out wire, and ground the IAC valve to the engine block on the negative side?

You ned to replace the FIDLE transistor with a TIP122 and wire the FIDLE pin to the negative pin of the ISV, the other ISV pin goes to 12v live after ignition.

Anyone use a VW ISV valve as a replacement for Fiddle?
