ok i have a 1990 ls motor from a integra. i am putting it in my 94 civic dx. if i am useing the d15b engine wiring harness on the ls motor will the 92-95 integra ecu's plug right in or do i need to do some re-pinning? the car is obd1 the engine is obd0. but i am useing newer model stuff on the motor. so i just need to know what ecu will plug right in with no rewiring anything.
