The presure sensor is the black cable that can be seen in th ephotos, also you can see the soldered sensor righjt after the blue hose in the intercooler itself.
I guess it works good, because yesterday I tested the conections and went uphill and wide open throttle, I hit 18 PSI continuos and no problems...highly recomended a FMIC if you have chip and other performance upgrades...
That's awesome, going to be a great finished car I'm sure.
The factory RSi wheels will make it just right.
Be patient, you'll have all those parts home soon enough.
Then post all the pics and how you do it.
Good luck, I am in envy, the RSi is a sweet looking NB.
