Ok... I got the diagram from LIPS, and it is in Japaneese... with translations into English. Here is what I have gotten out of it so far... (with cross ref to helm electrical manual).

Connector C (Blue) 31 Pin

Pin 27 Red/Blk (TPS) -> Throttle Position Sensor
Pin 17 Grn/Red (MAP) -> MAP "Manifold Air Pressure"
Pin 10 Blu/Blk (VTM) -> VTM "???"


Connector B(Gray) 25 Pin

Pin 12 Grn/Yel (VTS) -> VTec Solenoid
Pin 13 --- -> ?????
Pin 2 Blk (G101) -> Ground
Pin 1 Yel/Blk (IGP1) -> Ignition Power

Connector A (Gray) 32 Pin

Pin 19 Blue (NEP) -> ????


Ok here is what I am looking for:

Connector B (25 Pin Gray) Apiex instructions say that this pin (pin 13) is for "return signal", I have looked at the Honda Civic hookup (which is very close to the S2000) and it is labeled RPM... However on the S2000 there is no connection or wire there on the connector

Connector A (32 Pin Gray) Apiex instructions say that this pin (pin 19) is for return signal, What is this connection?????

I am missing the RPM signal on the ECU??? Is it one of these connections...

Any help would be appreciated.....

Dale, RPM is off Pin A19
Also, B20 is the "correct" Ground (B2 is an ECU Ground as well, along with B10 and B22 but the "correct" diagram to use ID's B20)
Believe it or not, the "correct" diagram to use is the one that is for the 2000 V-6 Accord (WH-4)
Feel free to PM me if you have other ?'s

 

Thank's RT... Went back and looked at the WH-4 connections... It is indeed the right one. I did not have the updated list. Thanks for the clarification. Funny thing about the ground is that they are all tied together on the ECU circuit board B2, B10, and B20. I will use B20 though, just to keep thing's right!!!

Again, thanks for the help.
