HI guys, does anyone know if the ecu pin out on Eudm obd1 4th gen BB3 prelude 2.0ltr is different to Usdm /Canada/ Jdm, as iv'e found that my vtec solenoid port has a different wire in the A4 position,
The history is iv'e dropped a H22A4 engine in a Eudm BB3 which does not have vtec, i have added the extra wires from the vtec sol. and switch also iv'e fitted a knock sensor and wired it up to the ecu.
Iv'e managed to get a P13 ecu for the change, but its my harness that's the trouble,

I am desperate for info please, even Honda UK could not help me with manuals ect.
