IF anyone can help PLEASE......
Yes my friends, I have searched & searched. I just get more & more confused. I am (hoping) someone can explain it to me like I am 5 yrs. old. AND understand I am looking for the easiest and least (safety minded) way to do this. I see all the posts with the E-Brake wires being tapped and transmission position...tapped (you know..all factory or safety minded stuff being done). I also found what I thought was going to be the "one for me" because it was for a 2003 (possible E-350) year and seemed to just require tapping into a few wires near the throttle pedal and sending them through a couple pots. (potentiometers) and a DPDT switch.Gave the color of wires and everything...
Well I took my pedal off today and unwrapped the wires. They were different colors and wrong number of them. Here's what I (think) I have...
There are TWO wires that seem to go to what I believe is the IVS (Idle validation switch) Naturally there is a plug to disconnect just above the pedal...Above the plug they are...
1.(RED)
2.(RED/green trace).
Seems simple enough....either a simple continuity circuit OR a Ohms/resistance difference based on weather the switch is one way or the other, and sends that value back to the PCM for processing.
Then you got the TPS (Throttle position switch). This has THREE wires and I assume is basically a potentiometer device also sending ohms values to the PCM based on where the pedal position is. Wires are...
1.(Yellow with Blk. Tracer)
2.(Gray)
3.(Black with White Tracer)
Based on the information I had read from that other post I figured I would stop into my local Radio Shack and get the Two (pots) suggested
of values of 10K and 50 K. My impression is that the 10k is used as a (trimmer) or (first adjustment) resistor. Then you use the second 50 K as the one you mount on the dash with a knob. If you are not getting the range you want on the dash knob you re
adjust the first (trimmer) resistor and try the dash knob again and see what you get for RPM idle at full left position and RPM high idle at full right deflection. Of course there is also the DPDT to turn these new tapped resistor circuits on and off. Seemed to make scene....Cheap, easy and no relays or e-brake or transmission taps... (In other words, We don't need any stink'in safety devices). BUT all this comes crashing down when I find I don't have thw wires or colors (HE) calls for in his EASY, CHEAP, AIC Mod post!
HIS INSTRUCTIONS......
Well if you are out there Rob Milnes and are part of this forum...I sure hope you will respond. OR I HOPE there is some one here that is knowledgeable enough about the workings of this seemingly (pretty straight forward) fly by wire throttle and it's signals to the PCM and how I might "tap" into any of those Three wires and possibly also the TWO that go the the IVS so I can "TRICK" the PCM into idling up because I am now sending the signals through those 10K and 50 K adjustable (pots).??????
MOSTLY....I don;t want to FRY my PCM or even my Throttle pedal's switch's. I don't ( with my limited knowledge) think tapping into them would "FRY" anything but hey, That's why I am here asking in this short story book question about how I might be able to do it with what I got or if I need different size (pots) and a different plan of action. I want to keep it as simple as possible! I've seen some of the schematics for (factory) wiring for ambulance & two truck idle increases. There all involved with SAFETY!! Not what I am looking for. NEITHER the $75 or more OBD plug in's OR the $600 Factory (upfitter) switch's...
Any one still reading?? LOL Thanks for the time and any responses. DDT

HIS INSTRUCTIONS......
- 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
