Throttle switch/ high idle control

Ok. I didnt see a heading in the tech folder, buy im wondering if theres a way to put in a throttle lock in? In semis i have driven, there is a throttle up/lock capability, which i have found myself wishing for in my e99 more than a couple times. Any links or info greatly appreciated. Tia

There is a factory cold weather Controller that will automatically hold voltage or RPM.
There are also some tunes that will do it.

There is an easy DIY with a potentiometer with switch (all-in-one unit) that I can't seem to find right now. The potentiometer fools the PCM into thinking it is getting a pedal signal. The switch is to fool the PCM into thinking the IVS (Idle Validation Switch) isn't triggered. I built one and used it successfully for years. Then I discovered my tuner has a high-idle tune so I removed it. You can have my old one for free if you pay shipping.

Ok,i try to twist it from the iron wire for you:

Buy a chip,hydra for example and you can choose up to 15 different rpm tunes to it.

Or buy factory AIC controller,looks like this:

Or if High Idle is all your after, buy a TS Chip for cheap and be done with it. Hydra is overkill and unnecessary in this case.

The Hydra has 3 high idle tunes to select from when looking at PHP tunes which come with the purchase price of the chip.

Not for automatic transmission, but I found a loose wire right next to the OBDII port on the V-10 I bought while correcting a hack to the OBDII wires. My 2001 7.3 has the same wire. The service manual section 22-21 for the 6.8 fuel shows the wire circuit #322 LB/YE to be for PTO unit.
I found the following link too.

High Idle Mod
