guys, pls help me sort out the problem with my hks evc. ive cleaned it, cleaned the connections and dont know how to connect it properly. i know i got 3 ports- 2 big and 1 small.
evo 4 is that the internal westgate (single port actuator) or external westgate (dual port actuator)???

in my case i got connected small port to the dump valve via Tee Y and to the manifold (1st port after the throttle body), but i also got connected turbo pressure gauge to the same manifold port. in this case i will need two Tee Y splitters (1 by the dump valve and 2nd by the manifold- to connect the pressure gauge).
2nd port (big middle) goes to the pressurised source.
3rd port goes to the westgate actuator and the 3rd port seems to be the easiest to connect

thx guys for helpin me!!!!!
