vtec question

b16a2 into a 95 civic is a breeze, not a whole lot of wiring to be done, i think there is about 4 wires for vtec, just need to run them through the fire wall and put them where they go, now where it gets complicated in terms of wiring is when you only have 2 injectors in your car(dual point) and your wiring for port injection, been there, done that, it sucked!!!!!!!!!! being a 95, it should already have port injection, so all you have to worry about is the 4 vtec wires
