Trying to help friend with a 99 civic dx. I have tryed to research wire harness for the car and so on and so forth. The car had a 95 gsr motor in it and it blew. He bought a 93 honda civic d16y6 or z6b motor. Was wondering where I could find out how to wire up the motor for his car or what needs to be done as far as the wiring goes. He has the motor swap with a obd 1 p28 ecu. Thanks for the help guys
