white to turbo compresser. black to wastegate. remove the stock vac lines that go from compressror to wastegate

I guess I can help you answer some of these questions.

The gauge is entirely manual, no electronics whatsoever.



Like scott said, goes to the compressor and wastegate. There is a line on there right now bypassing it. Just remove that one and run it to there. There are holes int he firewall already for it up near the steering column.
