Hi all. I have just purchased an Mk2 golf 20v. At present I belive it has a boost leak I my making 4psi. Disconnected n75 hoping it was that but there must be a leak somewhere. So I thought I would plug in a scanner to check faults and I can't find the port anywhere. The car is running a Mk4 ecu and loom. Does anybody know how to connect an obd2 port to the loom and is it a biggie. Cause after the boost leak is fixed I will be looking to map it but with out the port I'm knackered. Thanks in advance Lewis.
