high idle mod?

[03-6.0PSD]

I want this high idle mod every one talks about.

What is it, and how do I get it?

can it be done by me, or will I need a tech to do it? I see a fair bit of people have it, and I want it. Thanks in advance

You can do it yourself with about $5 in materials. All you need is a short length of wire, a toggle switch (use factory up-fitters if you have them) and a cheap inline fuse. Basically you run the wire from the 12v hot wire located at your OBDII port to the PTO power wire located right behind your fuse panel. Put the switch and fuse in the line somewhere of course and mount it... Have your truck in park, engage the E-brake, flip the switch and it will idle up to about 1200 rpm's. I know theres a good write up on it somewhere but I can't seem to find it right now, maybe someone else can hook you up with it. Otherwise I'd be happy to talk you through it when you're ready to do it as well. Let me know if you need anything further.

Ok so question about the wires.

My truck is an 03 F-350 6.0L

What colours will I be looking at for wires?

I found so far the live wire by the OBDII port is blue with a piece of tape over the end. I tested it, and it is live.

Now I dont know where the "PTO" wire is.

All I have found is the wires coming off the Parking brake switch/sensor. is this what your talking about? the wires are, lime green with a purple stripe, and a pink wire with orange stripe. Am I completly missing the PTO wire or is it one of those for the P brake?

Also I herd some guys talking about running a wire to a fuse in the fuse panel?

Does anyone have pictures I really need pictures right now. lol.

on an 03 model you shouldn't have to set your e-brake for it to work.,..i don't, but on the newer ones, you do have to.
