The bottom goes to the vent. OUT goes to the device being controlled.

There is a test for the wastegate tranducer voltage on ECU pins 53 and 37 (+4 volts at idle and -3v at 1500-3000rpm). Second half of test is to see pressure drops too.

PM me your email and I cant send it to you if you like.

I'm trying to figure mine out now too; new transducer doesnt seem to have helped; may be the vacuum pump.
