Attention: TDR Forum Junkies 
I have been looking into installing the "High Idle" feature on my truck and this is what I have determined after talking with Dave in the vehicle unfitting department at Dodge. I am installing this on a 07 3500 PU with a 6. 7L and 6 spd manual.
Installing on 5. 9 you need to ground wire #22 on the #2 ECU plug
Installing on 6. 7 you need to ground wire #15 on the #2 ECU Plug. There is already a wire in the plug you you will want to tap into it. I was told that the wire goes to the headlamp and dish area but we were unable to track it's final location in the cab.
This plug should be the one that is closest to the fire wall.
This wire is an 18ga DG/OR Be extra careful because #15 on plug #1 is VT/OR which is the electronic thottle control and can be easily confused. The best way to tell you have the correct wire is in the same row as wire #15 Wires # 11 - 14 are empty.
The only other thing you have to do after this is to have the dealer turn on the option in the computer
