ok i did a lot of civic h22 swap but now im about to swap a h22 in my h23
4ws it shoulb be easy a bolt on thing but i have a little proble with the ecu when i look on the net i found this ecu for the 4ws h22 the number is 37820-p13-j00 and it's write 4w on it it's a ecu for a manual trans but they have 4 plug on it like a auto trans.... and when i look to the wiring diagram the 4ws control unit and ecu dont share any wire exept for the vss... so do i have to use this ecu or a normal p13 will do the job

and what is the difference between this to ecu

I did the same swap. you just use the regular P13 ecu with it. The 4ws is controlled completely by the separate control unit.
