Had a couple people PM me lately on V-AFC wiring so I thought I'd post something the SEARCH could grab hold of
For the S2000 use Apexi's WH-4 diagram off their website. Hard as hell to read but I couldn't find the cleaned-up version someone cooked-up and posted ages ago. If some one saved it, maybe they could post it to this thread.

Here's the pin-out info in the form "V-AFC wire color; Function; ECU plug/pin (or device); S2000 wire color":

Red; Power; ECU B1; Yellow w/ Black stripe (splice in)
Orange; Power; ECU B1; Yellow w/ Black stripe (splice in)
Black; Ground; ECU B20; Brown w/ Yellow stripe (splice in)
Brown; Ground; ECU B20; Brown w/ Yellow stripe (splice in between V-AFC Black wire and ECU)
Green; RPM Signal; ECU A19; Blue (splice in)
Grey; TPS; ECU C27; Red w/ Black stripe (splice in)
Blue; VTM Signal; ECU C10; Blue w/ Black stripe (cut ECU wire and connect to ECU side)
Purple; VTi; ECU B12; Green w/ Yellow stripe (cut ECU wire and connect to ECU side)
Pink; VTo; VTEC Solenoid; Green w/ Yellow stripe (cut ECU wire and connect to VTEC solenoid side)
Yellow; MAP output; ECU C17; Green w/ Red stripe (cut ECU wire and connect to ECU side)
White; MAP input; MAP Sensor; Green w/ Red stripe (cut ECU wire and connect to MAP side)

Now, somebody better double check my work before ............. a car blows up

Randy, maybe you could FAQ this info

Just to make some notations. Your showing the orange and red wires getting tied to the same Yellow w/ black stripe? Same goes for the black and brown wire but the brown goes closer to the ECU.

If you will make notations as to which wires correspond to this picture I will edit and re-post the picture with color codes/some instruction.

I hope to see my VAFC in the next few days and to have it all wired up by this weekend. As for when it will get tuned..........WHO KNOWS!!!! IT HAS TO GET WARM FIRST!

Which brings me to a question. I will be playing with Air/Fuel curves. With rises and falls of air temps will the air/fuel ratio's change as well? Being here in CT we have very WIDE fluctuations in temps. Will I need to keep multiple settings for say a 50 degree day a 80 degree day?

Thanks.

Well now I need a part too. Hopefully the seller will give me the part but who knows. https://www.s2ki.com/forums/showthread.php?...threadid=102223
