. If you have the 4 aux switches , you can make aux 4 the high idle mod , I just did this tonight on my truck . You take the orange/blue wire from behind the fuse box (1 of 4 wires of the aux switches) Then you extend that wire down to the 11 wires (beside the ebrake) and hook it onto the purple/green(may be purple/blue i cant remember) . Then your done . Make sure the EBRAKE is set , and the trucks in PARK or Neutral , and hit the aux 4 switch up and the idle goes up to around 12-1300rpms (sometimes higher) for like pto(power take off) or to just warm the truck faster or cold winter days .
But im sure there is a how to on here somewhere. Good Luck
