Then you also need to get the EGR control box (black box that mounts to the firewall with vacuum tubes going in and out) and wire that in as well. Honda for some reason sends the 2 wires that control this thing not through the engine harness but through the wiper harness that goes through the firewall on the driverside. Annoying.
