I have a used NOS brand window switch that I had with a nitrous kit I used on a previous car. It has pills to turn on at 3000 and off at 6000. The pills can be changed to what ever you want. I think I paid around $150 for it new, I will take $100 shipped plus the 3% paypal fee. PM me if interested. Thanks.
