High Idle mod

$

My truck, has the 6 speed manual tranny. If I start the engine on a cold morning say less than 40* or so It will idle a couple hundred rpms faster than when its at normal operating temp. I suspect this is a computer controlled higher idle for the temp. If I touch the clutch or brake it slows down to normal idle.

If I do the High idle mod to the upfitter switch AUX4 on the dash does this delete or do away with the high idle that is done automatically when it's cold?
I say #4 because I think its the 10 amp switch in the 4 switch panel. I believe I read that 1 and 2 are 30 amp and 3 is a 20 amp. I could be wrong on this....Thanks and Merry Christmas! Hope Santa brings us all the cool mods we want/need. :thup:
