Does anyone know what each wire hooks up to? A friend of mine gave me his, but I have no idea where the wires hook up. I was thinking that there should be some kinda connector at the end, but there isn't one. Heres a pic of what I'm talking about. If I can't figure it out, then I'm just going to sell it.

 

Uhm, sorry to tell you this but the wiring harness on your V-AFC is really messed up. It's usually at least 1/2 a foot longer and it goes into a connector which connects to the lower portion of the ECU harness and then that part connects to the ECU. w/o extending any of the wires I don't even see how that V-AFC can connect to the ECU. Without pulling out my V-AFC I have no clue which wire goes to where.

 

Lordvtec and I know.
Let my gather all my info together and I type you up something. If you do it the way the instruction says (that I'm about to give you) the VAFC will work with no check engine and no problems at all.

This a diagram of the ECU and the pin # if you look on the back of the connector once you unconnect them there are numbers on the. The colors on the diagram indicate the color of the wire for the ecu that you'll have to hack into.

----------------------
On pin 32:
Slot # 8: The wire for the ECU should be GRN/YEL (this is the VTEC signal)
The Pink and the Purple wires from the VAFC connect to this.
To install: CUT the GRN/YEL wire so that you have to ends (an input and output). Attach the Purple to the INPUT end (the wire going towards the ECU) Attach the Pink wire to the OUTPUT end of the other end of the wire you just CUT. (output being the one that goes away from teh ECU.)
------------
Slot # 10: The wire for the ECU should be BLK (ground)
To install: Splice two attachment points one relitively close to the ECU, the other about 2"-3" from the one you just spliced. Attached the BRN wire form the VAFC to the splice closest to the ECU ***IMPORTANT TO DO SO***. Attach the BLK wire form the VAFC to the other splice.
----------------
Slot # 11: The wire for the ECU should be YEL/BLK (power)
To install:Again Splice two attachment points (you don't need one to be close to ECU. Attach the ORN wire from the VAFC to the splice closest to the ECU. Attach the the RED wire from the VAFC to the other splice.
---------------
Slot # 20: THe wire for the ECU should be YEL/GRN (RPM signal)
To install: Splice the wire then attach the GRN wire from the VAFC to that wire.
---------------------------------------------------------------------
Pin 31:
Slot #15: The wire for the ECU should be BLU/BLK (VTM signal *VTEC Pressure*
To install: CUT the wire so that there are two piece (like in the instructions for slot # 8.) then attach the BLU wire from the VAFC to the wire that goes towards the ECU.
****only wire on pin 31******
----------------------------------------------------------------
Pin 16:
Slot # 1: The wire for the ECU should be REd/BLK (throttle Singal)
To install: splice the wire then attach the GRY wire from the VAFC to it.
-----------------
Slot # 3: The wire for the ECU should be RED/GRN ((Pressure)
To install: CUT the wire again like slot # 8 so that you have two pieces. Attach the YEL wire from the VAFC to the input wire (wire going towards the ECU)
Attach teh WHT wire form the VAFC to the output wire (wire going away from the ECU.

-------------------------------------------------
Before you begin splicing into your VAFC I'd high recommend that you do a couple of things
1.) review the Apexi instruction as the other guy provided you a link to.
2.) Know what wires are what before you splice into them.
3.) Work in a warm environment as the wires with be easier to splice into.

********I'm not responsible for any mistakes that you make. My instruction are correct as I cross referenced them with the Apexi*************

 

Thanks for the site...i needed that

 

Dont forget http://members.aol.com/ryoucold/prelude/apexi/

very helpful

 

Oh yeah you're fucked, the wiring should be much longer.

 

Hey Ryan: love the diagram.. you enjoying that vafc?? I was just searching for the old post i put up before regarding the install, but noticed you beat me to the punch.. (i think i like your diagram better than mine.. lol)

 

Hey LordVtec: Remember I said I had differences between your installation and my installation.....well I got really lazy and crunched for school work so I never got to telling you what the difference was. Anyways there's two issues.
1.) Slot # 3 on pin 16: The VAFCs instructions read to put the yellow for the input wire and the white for the output wire. Yours said to do the opposite. Might wanna check your instruction and possible your install .
2.) Slot # 15 on 31: Kind of simple you didn't mention that you need to cut that wire and attach the blue wire from the VAFC to the input side.

That's it.
