Hi, i bought gsr B18c1 motor that i told was out of 96 GSR, it came with a harness. My question: i dont see the plug for 02 sensor and the stock manifold that it came with does not have a o2 in it. Iam putting the motor in a 97 Civic EX, can i use stock harness of my civic. What do i need to convert this motor to OBD2.
