For the KS and IAB wiring, if your engine came with the plugs already, and you plan on reusing your stock EX harness, then just cut off the two plugs and wires from the B18. Those two wires will have to be run from the sensors, through the firewall, then into the ECU. Going into the ecu you have two choices: get ecu pins from a junkyard, solder them on to the wires then plug in. The other option is to just jam the wires into the ecu plugs (worked for me).
