High Idle

[wxmn6]

I'm still a newbie with my first new truck. '02 2500HD 6.0L gas. I was surprised that 2500HD and 3500 could have high idle switch. I just never thought that they would have it. What I would like to know is if it is benefit to have high idle on our truck? Why is it a good idea to have one, and what do you use it for? It got me interesting and I would like to hear more about it.

The only reason I have it is for faster warm-up on cold mornings, holding heat in the motor while loading and unloading in winter, and running the A/C on hot days while unloading or loading freight as it works better if the rpm's are faster. A/C doesn't work well if idleing. I do plan on installing a PTO at a later date also.

Where can I get the instruction for wiring a high idle switch on my '02 6.0L gas truck? Thanks.
