I am looking to try and find a complete ECU pinout guide, not just for like a A/F guage, or VAFC, but I would like to know what every pin is for. I am thinking of making my own monitoring system, and would like to know what every pin on the ecu in my 98 SH is for. Does anyone have a guide on the whole ECU? Also, what is the box next to the Ecu for? there are 3 boxes in the ECU area of the car. the Ecu, one smaller one mounted next to it (ATTS box?) and then one mounted on the right side wall behind a kick panel. what are these other 2 for?

Thanks for your help guys and girls!!!

I have a regular prelude...but not the SH

 

There's a complete pinout diagram in the 1997-99 Prelude factory service manual...
