Installing Harness removing stock seatbelts

I wanted to know from the members that have aftermarket seats and used four point harness. How they removed the automatic clip that on the body of the car, you know the one that goes up when doors open and down when closed. How do you remove them also how do you make it so your seatbelt light doesn;t come on, on the gauge cluster. other then removing the cluster and just taking the bulb out. Thanks.:slight_smile:
