so a prefacelift loom will plug straight into the 98 b18c ecu but the facelift one wont?
Thanks
your b16b ecu should be OBDIIb which means the Harness which ur using assuming is ur ek9 harness will plug and play, only thing is a b18c ecu is different to a b16b ecu it'll work and run for sure, not as smooth maybe but still will do the job. you can use the 98 spec harness as well and then just use the 98 spec ecu its 1am i hope i wrote something that made sense
