Alright lads i know this is been done too many times to be fair but i cant find the info that i need, so basically i have a 2000 ej9 1.4, ive swapped a b18c from a 98 spec dc2 and 4.4 lsd s80 box, my only question is that my own 1.4 dash loom has a plug that cannot plug into my p73 ecu because my ek4 vti obd2a engine loom has 3 plugs which all plug into my ecu, but there is only 3 plugs that go in to it, so im left with the plug from my dash loom just hanging about, everything works bar the fuel pump and i belive that plug is what turns on the relay, so would i be better off swapping the dash loom for an obd2a one or is there a converaion harness i can get? thanks lads
 
You have the wrong loom, you need obd2b from a ek/ek9 facelift an its plug an play

You will need obd2b to obd2a conversion harness
 
Yep figured that out mate, i managed to get everything sorted, didn't need to get a obd2b loom after all only difference between the two that i could find was connector A was part of the dash loom on obd2b and part of the engine loom on obd2a, just a case of chopping the connector from the dash loom and solder a few wires together on engine loom connector A, ecu pinouts sticky was my bible
:thanks::bow:
