Clutch pedal questions

[yzstud]

I rewired my clutch pedal switch(the black sensor) and noticed that other gray sensor and had some questions about it
so, in the process of installing the clutch pedal on my 95 atx-mtx swap, I noticed that extra sensor, the book calls it the idle control switch, I do not have that part of the harness in my atx car, and i was wondering what will happen if i don't have it hooked up?
Does it adjust the idle when the clutch pedal is pushed in?
Will it be all that noticable?

If its anything like a mustang, you will have a varying idle. The revs will rise and fall to the point where the car may shut off. I know that in mustangs, that connector can be jumpered, and you wont have idle issues
