Has anyone installed a vafc successfully on a 99 si here? If so which wiring diagram did you use? I have downloaded two versions of the vafc manual and both have 4 plugs showing for my ecu (a 32 pin, 25 pin , 31 pin, and a 16 pin) my ecu only has 3 harnesses not 4. Any help on this would be greatly appreciated. I have searched it and found nothing. This is the stock ecu in a 1999si.

visit http://www.apexi-usa.com and go under documentation. Its right in there, and clearly shows the SI if i recall correctly. Installation is quite simple, just use Pr 6 for in and out.

Yeah I am looking at the diagram right now and looking at my ecu. The diagram shows 4 harnesses and my ecu only has 3.

need some more input on this plz guys. This is frustrating that the diagram I look at has 4 harnesses and all of the other diagrams don't look remotely like my ECU.

Anyone maybe have some pics of their wiring setup on their 99-00 si? This would do wonders for my installation cuz basically I am stuck. I got the diagrams but don't know which wires to splice cuz my ecu doesn't match the one in the diagram =/

Kamin

you have 4 plugs on the ecu but only 3 are used, right?

sinatra

Correct.

Kamin

then the 3 they are talking about are the 3 wiring connectors ignore the blank space.

the wiring on their site is correct.
