Are those the only wires we use? I'm not sure about the input and output wires... btw I got my vafc2 used. So I have no manual.
are the pink and yellow wires used?

Rep Power: 0 ohhhh I see... you cut the wire, and put it to the input, then the output wire goes back to the ecu.

Rep Power: 240 unless you know exactly what ur doing I would not do this urself. when I tried I didnt get the wires right and when the enginestarted it was bad. so I took iot in had it done right and had it dynoed. If you dont get ur car dynoed and set up correctley then u will never be able to lower your engagment point. after the dyno I am now able to kick the vtec in at 2400 and low cam kicks in at 2200. and now when the vtec kicks in I can tell a huge difference when I start to pull out of 1st gear. definatley get it to a dyno.

Rep Power: 788 if you can't follow that detailed post with all the info there, you shouldn't install it. Its just a very easy thing to mess up and then you'll be out $1000 for a new ecu. I sure hope you remember to unplug the battery because those are LIVE wires that can kill you! Honestly, its not worth it. I had mine dyno tuned, gained 2whp with some moderate engine work. Changed one little thing and now the a/f is way off again and needs to be retuned. as for vtec engagement, its a very bad idea to change it. alot of conditions need to be met before the stock ecu can activate it such as oil pressure, full throttle, rpm, etc. it can be very bad if you just set it to engage at one rpm instead of variable and it can ruin your engine if it engages at lower oil pressure.

Rep Power: 356 eww why vafcII for turbo you should have just saved a little more. really the only good thing it is good for is for lx/dx to ex head swap. kind of like me but im running a dx ecu with a d17a2.
