I have a 95 civic EX with a OBD1 P72. I know I have to run my knock sensor wire and my IAB sensor wire. The thing is I dont know where to start. I know that the IAB goes to A17 and the knock sensor goes to D3, but the thing is... I dont know where they go from there. How am I supposed to get the wire in there? Do I stick the wire in the harness?? Also where do those wires go to?? Where on the motor or wiring harness do they connect to??
