today i looked at the electrical harness behind my turbo, you know, the red one. anyway its supposed to have 2 lines coming out the back of it. it has the line nearest to the manifold which runs down to the Y fitting and the compressor/wastegate housings. but it is missing the other line. what is this line and where does it hook up. please help. could this be the reson im only currently running 10 PSI!
