hi idle mod question

[GRI]

I just spent 1.5 hours looking for this.
I read the TSB and it confused me more. Is it as simple as hooking two wires to each other?
the yellow green wire and the brown wire for the #4 upfitter?
if so. I know where the brown wire is where is the yellow green wire


thanks guys

Yes it is just hooking up two wires. Both bundles are right above the e brake pedal. One bundle has 12 or 14 wires and the other bundle has 4 wires which is the wires for the upfitter switches. Try powerstroke nation. They have a tech file there with pictures. It makes it pretty easy.

My high idle throws a wrench light the odd time I think p162e or something. I just clear it and it works. Anyone else got that

[GRI]

I didn't notice it on mine

Prevents wet stacking. It's easier for you to google it. I'm sure there are some great articles online about diesels and wet stacking.

Interesting, I thought it was used to warm your engine up in cold weather. Considering these trucks were designed to pour fuel into the exhaust I wouldn't "Wet stacking" would be an issue.
