The ignition control unit is at the upper right of the steering column.Pull the underdash panel and look up.Connector wire #7 org should show continuity to ground with an ohm meter at idle and slight resistance with the accelorator pressed.This checks the throttle switch adjustment and wiring.#12 Blk and #13 green go to the knock sensor.Disconnect the knock sensor and check #12/#13 at ECU with meter and it should show open.If thats OK then jumper Knck sensor connector and check for continuity between 12/13 at ECU.Theese test should be with the ignition OFF.Other inputs are RPM sensor,Coolant sensor,FI ECU,EGR sensor(if it has one).Good luck
