Sorry for the delay, I didn't get a notification of your reply. The Intelletronix switch works fine. The window switch will shut the clutch off at a set higher rpm but some of them won't turn it back on until the car is restarted. I think it's the Jegs window switch. The best one would probably be the Summit switch because it can be set as low as 1500 rpm although the Intelletronix says 2000 I set it at 1600 and it works there. I need two more and I'll probably get the standard Summit switch because there really isn't a need to shut it off at higher rpms although the cost is the same. The one thing you have to do is run it through a relay and have the blue wire from the switch go to the black (ground) of the relay and have the ground of the relay trigger the circuit on and off in the switch. It really is nice to not have to worry the aircon will kill the idle when coming to a traffic light or stop sign. Although I have a 65 amp alternator just the fans in the evaporator and on the condenser draw enough current to draw the idle down a couple of hundred rpm at idle so I have the idle set at 1000 with the air off. I was surprised it draws so much.
The passenger seat is 15 miles an hour faster than the drivers seat.
