2 options really. It connects to the boost pressure sensor which usually has a vacuum line going into the upper intake manifold, or alternatively the nipple just below that. When it does that it then reconnects up to the main harness which goes through the firewall and to the ECU. The pressure sensor is bolted onto the front driver's side strut tower on the front side of it, close to the headlight. I'm saying this from a Japanese point of view though; you'd probably see it on the passenger side.

Alternatively, (and I think in the case of some HKS models and maybe an RE Ameniya one) it connects much closer to the ECU, or even next to it, and splices into the wire from said boost sensor.

Why, are there other places it will connect? Maybe you can enlighten me.

EDIT: Reading your post again, maybe you're asking me if I know where the pins from the FCD (and therefore boost sensor) go. If so then one I believe is to ground, one will go to a constant voltage (5V sticks in my mind), and the other pin will give a varying voltage depending on the pressure detected. Is that what you're wanting to know?
