I have a 94 Del Sol S that has the D15 in it. I'm putting a B16a2 in it. I have the wiring out of a 93 Del Sol Si as well as the ECU out of it....The Harness will work for the engine but I have to add a knock sensor wire Correct? Now, the ecu is getting the HOndata stage 4 treatment to it. My question is if I add a knock sensor wire to the ecu 1)where do I put it and 2) will the ecu I have know what to do with it?
