what do i need to do to reverse the signalfor the IAB? im putting a 97 b18c1 into a 92 cx using an obdI ecu. i looked for the wires and it doesnt seem like the colors are what they are supposed to be. i thought with a 92 i would only need to run one wire? or do i need to switch one and run one for knock sensor?

 

you switch the a20 pin at the ecu to a17...thats your IAB wire. for the knock sensor, you need a to run a wire from the sensor (red/blue) to the ecu (d3).
