i have a 91 integra and i have a 96 b18b engine that i want to swap in it. well so far i was told i need to use my old injectors, fuel rail, throttle body and harness. but when i put my old harness i noticed that the new block has less sensors on it and my harness doesn't have some of the connectors to sum of the sensors on the block. so somebody plz help me. thx p.s. i am also lookin for used headers if anyone has one.
