I'm pretty sure I found this on dieselstop but I was curious what everyone thought about what this guy did.
http://www.northtexaspowerstrokes.com/mods/aic/
Seems to be pretty well documented and straight forward. I looked at the factory AIC and saw some on ebay but they seem a little bulky and around 200 bucks. This method is small and very cheep. What do you guys think... should I give it a try? On another note how much fuel do you think the 7.3L PSD burns when at an elevated idle say.. 1200rpm? |

Yeap I've known of Kevin's AIC DIY for a few years now,that verison is for 94-97 SuperDuties.
I can post or email the 99-04 version if need.

Yes please post! I would like to make this. Do you know if this will work on a '97 E-series van? My dad has a diesel (7.3L PSD) sportsmobile and wants an idle controller. I was going to make him one. |

If the mod can be done the same with the E series AIC you may want to contact BigK for further info to be 100% sure it applies the same; kevin@northtexaspowerstrokes.com
These instructions are noted as to 2004 but it's actually 2003 with the 7.3L engine
| Quote: | [b]1999-2004 $10/$15 AIC
Source: Rob Milnes
It should not be used as a low speed cruise control for safety reasons. Neither the $10 or the $15 will disengage if the brakes are applied. If there is enough interest, I will design an AIC that can only be used when the parking brake is set.
Why you might want to buy the Ford AIC
* It can automatically put your truck into high idle when the parking brake is applied
* It has a digital display
* It will hold an exact RPM. The $10/$15 will vary speed slightly as the engine warms/cools
* It has a warrenty
more info
If you're still with me, here's how to build your own.
Time required
About 1-2 hours
Items needed:
* R1 potentiometer with linear taper (see Table 1 for values)
* R2 potentiometer with linear taper (see Table 1 for values)
* 2 knobs for above potentiometers
* Double pole, single throw (DPST) switch
* 16 guage wires (4 colors: red, green, brown, grey)
* Electrical tape
* Heat shrink tubing
TABLE 1
Values for R1 & R2 potentiometers-----1999-2002 7.3 L--------2003 7.3 L
R1--------------------------------------------------------- 5K---------------------50K
R2----------------------------------------------------------5K---------------------10K
NOTE: This article is still a work in progress, so if you have done this to your truck please send me the R1 and R2 values you used.
When I installed my AIC on my 2003 7.3L, I found it needs vastly differnt R1 and R2 values than anything posted out there. I have the feeling that the 6.0 L's would need different values as well.
Extra items for $15 AIC:
* LED and holder
* 1N4004 Diode
* 680 ohm resistor
* 16 guage wire (red, black)
Tools required:
* multi-meter
* slot screwdriver
* wire strippers
* Soldering iron and solder
* adjustable wrench
* allen key
* lighter
* hack saw
* drill, dremel tool, etc as required to mount controls
$10 AIC procedure
Figure 1
$10 AIC
$10 AIC diagram
1. Locate the accelerator pedal and remove the 3 fasteners to remove it.
2. Locate the wires with the following colors in the wiring harness connected to the pedal:
* Red w/ yellow tracer
* Red w/ green tracer
* Brown w/ white tracer
* Grey w/ white tracer
3. Strip and solder approximately 2' (or more depending on where you want to mount the controls) of the following wires to the above wires:
* Yellow
* Green
* Brown
* Grey
4. Connect the yellow and green leads to one pole of the DPST switch (so that the yellow and green leads are electrically connected when the switch is on). Check with the multimeter.
5. Open fuse panel access cover on the driver's side
6. Connect the brown lead to the left terminal of the R1 potentiometer. Connect more brown wire to the center terminal of the R1 potentiometer.
7. Cut off excess post on the R1 potentiometer and mount it behind the fuse panel access cover. Install the knob with an allen key.
8. Connect the brown lead from the center of the R1 potentiometer to the other pole of the DPST switch.
9. Run a grey lead from the last terminal of the DPST switch to the left terminal of the R2 potentiometer.
10. Connect the grey lead from the accelerator pedal to the center terminal of the R2 potentiometer.
11. Ensure that all connections are not grounded or touching.
12. With the mulimeter, set the R1 potentiometer to half and the R2 potentiometer to 0 ohms.
13. Set the DPST switch to off.
Test and Tune
Start the truck and allow to idle for 1 min. Flip the DPST switch to on. Adjust the R1 potentiometer until idle speed is approximately 1100-1200 rpm. The full range of the R2 potentiometer should change the idle speed ~ 100 rpm. Once you are satisfied with the idle speed and range of adjustment, tape down the knob on the R1 potentiometer. Flip the DPST to off. Idle speed should return to 600-700 rpm.
final installation
14. Mount the DPST switch and R2 potentiometer as desired
15. Reinstall accelerator pedal
16. Heat shrink and/or tape all electrical connections and zip tie loose wires
17. Reinstall fuse panel access cover
18. Grab a cold one and admire your work
19. Take a picture of your install and email it to me!
$15 AIC procedure
This version adds an LED indicator that lights up with the AIC is in use.
Figure 2
$15 AIC
$15 AIC diagram
1. Follow steps 1-13 of the $10 AIC procedure.
2. Cut the green lead wire 1-2" from the DPST switch.
3. Solder the red lead and the anode (+) of the diode to the green lead coming from the DPST switch (double check this step)
4. Solder the Cathode (-) of the diode to the remaining green lead.
5. Solder the red lead to the (+) terminal of the LED
6. Solder the black wire to the (-) terminal of the LED
7. Connect this black lead to ground
8. Test and tune per $10 AIC
9. Use the LED holder to mount the LED during the final installation phase. [/b] |

Thanks a lot CHPMustang. Have you made one of these? I'll give it a try this weekend if I have time. |

I have not yet tackled this mod but it's certainly on the to-do list for sure!
Sorry for the long post but that's about the size of the mod
