1st Generation AFC owners.
my friend is looking for wireing order for first generation Apexi AFC.
it is the AFC that uses little dials to tune.
any one with this unit please help.
I want to know the wireing diagram for it.
the unit is going to be install on a USDM B16a motor.

Re: 1st Generation AFC owners.
Well, i hope you have your harness wired right, so here we go. you can go here and download it form there site.
http://www.apexi-usa.com/documentation.asp
But from what i remember there are only 4 wires that you have to find on your harness that you use for monitoring stuff. so put all wires that go to the same wire on harness put a inch apart. One is the IG power (red,orange-wires on v-afc) on 2 it, I used pin# A15. Another is the Ground (black,brown-wires on v-afc) on to it. Real important is to separate these wires a inch apart and put them real close to ECU, Real import. I used Pin# A2. Well the single wire to wire are easy. it RPM signal and Throttle signal. Throttle signal (gray-wire on vafc). i used pin# C7. For Rpm signal (green-wire on vafc) i used the negative signal coming from the coil in the distributer, its a negative signal for some reason. try and follow it as close back to the ECu as possible.. Then too the Vtec piggy back stuff. this is real easy what you do is wire it so the signal goes threw the Vafc before it goes to the Ecu. So it goes vtec pressure soleniod too vafc then to ecu, got it. Well I used pin# A8 for the Vtec soleniod signal,(purple,pink-wires on vafc). Ok so what you do is cut it and then connect the pink wire to the side that leads to the engine, and connect the purple wire to the side that has the harness conector on it, or that leads or connects to the ECU. you got that, OK. well we are making progress aren't we. Next is Pressure Signal(yellow,white-wires on vafc) i used pin# B5. the Yellow wire connects to the side closest or connects to ECU. The White wire connects to side that leads to engine. Then you put those connectors that came with the Vafc on the white yellow pink and purple wires. You then just plug the yellow to white wire together and the Pink to the Purple. See When you do that you complete the loop of the Vtec piggyback from ecu to vafc to sensors. The Blue wire (vafc) is the VTM wire. OBD-0 doesnt have VTM so you simple dont hook it up. Really you done, so the only thing that you have to watch out for is the grounds, you have to connect them closer to the ECu for a better ground. The rest is cake i think,But i have hooked up alot of them. When connecting the wires i would soldier and heat shrink everything, dont use those stupid butt connectors they suck. i have found the thing just works better, its a better connection when soldiering. Well thats all i got to say for now i'm in a hurry so go to apexi site and download the manuel and then just print page 11 of the manuel thats only one you need. and go to http://www.hondata.com/techwiringpw0.html and get the pinout diagram for wiring. and print it out,OK!!!!!! And when it comes on set it to 4 cylinder and throttle up with the arrow. its in car select screen. you'll understand when looking at it. so hopefully i told you right but double check everything i said and print those pages out and you'll probably understand it yourself and will not need our help. Im not the smartest thing so actually triple check me and ask some more ?s if needed. SO HTH
