Ok, out of curiosity i have this stupid question.
I know how to hook up an internal wastegate. The 1 Vac line on the wastegate goes to a charge pipe or the compressor housing of a turbo to read the boost. But on external wastegates, there are 2 hook ups. What do those do? 1 of them has to be to read boost measurements to push the spring, but what does the 2nd one do?
thanks....
