Head to 8 mins of this video, i used this little box.... then reset the system using INPA
literally about 4 seconds of this video and you'll see the box, i cut the wiring off the stock seat occupancy and soldered the connects this box ( meaning the car loom is untouched and it simply plugs in ). I also used all the stock seat belt reciprocals so no seat belt issues. Hope this helps. Prewarning fitting aftermarket seats to this car is a PITA, the pedals are offset and to get the seat centred to wheel etc take ALOT of time and effort, not to mention getting the electrics to play ball. GL DM if you need more info and maybe a like on the YT channel :-P
