I picked up a big shot plate system for my car, it has the WOT switch for mounting at the carb. I was planning on using a MSD rpm activated switch to turn the system on and was wondering if maybe I could use another one to turn it off to make sure it's not on if it hits the rev limiter. Is anyone here using the MSD rpm switch for nitrous activation? Nitrous and revlimiters don't mix from what I've been told. ????? Bob

I used the MSD window switch.It takes a pill for turning on and another for turning off.(1500 on and 6000 off).Was easy to wire up and works with all MSD pills.
