hello i was sold a d15b motor to replace my d16y8 because they didnt have any in stock so i swaped it and it ran shitty so i had the crankshaft sensor bypasssed because the d15b didnt come with it japan has diffrent smog regulations well i was driving one day and my ecu started smoking so i stoped unpluged it and drove again this time it melted the small plug into the ecu i had bought a ecu and a engine harness i replaced it but i wasnt getting power to the distriubtor so upon further inspection i also had melted wires under the dash to the fuse box i really would like to know the correct ecu to use and correct wire digram so i do not melt up again any help or hints will be greatly appreciated
