that sort of helps. it would make my life alot easier if some one has a picture of a complete uncut full harness and tells me which plugs/wires to change to make this work. ---

Remove every wire from car. Take tapeand mark all grounds and what goes to what. Remove s12 harness(and save this, you may need it) and then re install s13 harness to s12 and try and connect everything. ---

[http://ka-t.org/fsm.php](http://ka-t.org/fsm.php) download the s13 service manual and there are charts with every harness in the car, and what each plug does, etc. ---
