ok so i got a 1991 civic hatchback and i bought a b18b1 to put in it, its out of a 94 integra so its obd1 and my hatch is obd0. so i do not have the stock main harness or computer i want to convert the car to a true obd1 swap and use the main harness and the integra computer in the hatch but i never see anything written up about it everyone just use the obd0 harness on the engine and use a jumper harness and rewire some other stuff? so does anyone know anything about this i need help
