Civic EG

]hi, i just want to swap a d16 over a d15b carbs with an inline fuel pump( i don't wanna change the tank) and i wanna run the p28 on the loom using a harness conversion. The only prob i have is the carbs are running on p03 ecu which it has only 2 plugs that are fitting straight on p28. the problem is that i'm missing one plug!. i've got the obd0 to obd-1 but is not plug and play only because i need to chop off the missing plug. any idea will be great.


p03 ecu only 2 plugs



now the 2 plugs they fit on p28 which if my car was obd-0 it shouldn't fit

You need a conversion harnass for the ECU, from obd0 to obd1

I've got this already . the prob is that my car is not obd-0 , . My old ecu p03 has 2 plugs, to run the p28 i need 3 plugs. my internal loom is fitting p28 ecu, what i need is the 3-rd plug. some pics below

the plug from my loom not fitting in obd-0 obd-1 conversion!

Not to be fussy but I'm not reading green text on a green background.

So your options are to replace the harness or cut a third plug and wire it up (preferred).
