how do i wire vtec?

alright, my buddy has a b18a1 and im swapping it for him and putting a jdm b16a with ys1 tranny in for him and i was wondering how to wire the vtec solenoid up... is it three wires or 2... i've seen people say both... and i saw a wiring diagram a while back, but cant find it again... i looked at hondatech and it wouldnt let me search, everything came back blank.... i would greatly appreciate it if someone would tell me how to do it because i have to swap it tonight and finish it tomorro... im booked fully with LTI and HIN on saturday. any help would be great!!!!!! thanks!

There are 3 wires; 2 for the solenoid (1 of which is just a ground), and one for the pressure switch.
