High idle "mod" on a 6 speed..

Ok. I did the high idle "mod" today and it did nothing. I did some more homework and it turns out the manual trannys have that option disabled from the pcm. APPARENTLY the 05 and later pcms do not. So my question is it possible to have the pcm flashed with the 05 and later tune to fix this? Or possibly have a tuning shop put the tune in to make it work. I do not want to spend alot on a AIC. if it comes down to that ill just undo what i did and leave the truck alone.

What year is it? As far as I know the 03's and 04's will not react like the 05's and up do. However there is a plug for an apcm located on the bottom side of the steering column. I have hooked mine into a couple of early 6.0's when I was flushing the cooling systems and it controlled the rpms just like a 7.3.

I used the light blue with a yellow tracer by the parking brake and a white wire with a blue tracer by the OBD II connector.

I did look into that. However I am not buying another module to hook up. If that is what I need then ill just leave the truck as it is. To me it's not worth $1,100 just to make it high idle.

You can find them on ebay for a couple of hundred bucks. I think I paid 120 for mine.

I found this in the wiring diagram:

P T O Signal Wire to PCM and Customer Pass–Thru Wires: The location of circuit no. 322, Light Blue with Yellow Trace (LB/YE), has changed from its 1999 thru 2001 model years location. For 2002 model year the circuit is located to the left of the steering column and just right of the parking brake pedal, accessible through the modesty panel. The wire is still blunt cut, but no longer has an identification tag. The customer pass–thru circuits can be found with circuit no. 322. This circuit is only active on 2002 F–Super Duty models with automatic transmission and power take–off provision (order code 62R).

If I MUST get the box ill just leave it. I like the idea of a simple rocker switch. Not a whole module. And the diagram info is for a 7.3 it looks like. I have a 03 6.0.

This came out of a 2003 wiring diagram, I'm not sure why it says 2002. You can get the box and program it to adjust idle as soon as the parking brake is engaged and hide it under the dash, but this would be an issue with a manual trans. I have mine wired this way but I got an auto.

If i can hide it and hook it up to a switch ill just do that. I like that idea better. I honestly appreciate your time.

I know mine works on the 7.3's but it didn't respond automatically on a 6.0.
I got a friend with a 03 and another friend with a 04 so I'll have to dig out my newer apcm and program it. I'll let you know what happens so that you don't buy one and not have it work how you want.
