High Idle Mod
I've been doing a little bit of reading in here, and I've got some questions concering the high idle mod.
First, I want to make sure I understand the purpose of it. From what I've read, you should never let the engine idle for more than 10 minutes at "normal" rpm. I'm not 100% sure why, but I take it that it's bad for the engine. For various reasons, like warming the truck up on a cold morning, you may want to idle more than 10 minutes. This is when you'd use the high idle mod. Am I understanding correctly here?
Second, I'd like to know what's involved in doing the mod. I've got the upfitter switches, so it shouldn't be a big deal, huh? What's the procedure for doing this? Tie a couple of wires together? Is there a good, illustrated set of instructions somewhere? Are there any negatives to doing the mod?
Thanks in advance from a diesel newbie!
