Hi Idle Mod for Manual Tranny 6.0?

[05PSD]

Hi everyone,

Been doing lots of reading on here for the past months but never had anything to post till now. I was wondering if anyone had done the hi idle mod on a manual transmission 6 liter.

I used the AUX 4 switch to send power to the PTO wire (orange) but am getting nothing when I flip the switch. At the bottom of page 8 of this bulletin:

https://www.fleet.ford.com/truckbbas/non-html/Q108.pdf

it says that the manual transmission requires a resistor between PTO_VREF, PTO_RPM and PTO_GND. I was thinking that it would be cool to stick a potentiometer under the dash that was variable from 0-45kohms that I could change the idle speed with.

I was also curious if I just used the BCPSW wire (purple/lt. green) instead if I could get a 1200RPM idle without having to put a resistor in. Thanks for the help!

i just did the mod this weekend and i love it . i used a toggle switch and the purple /light green stripe wire because it is supposed to vary the rpm from 1200 to 2400 to keep the battery charged . the orange wire is pto and converter lock up . so use the purple/ light green stripe wire . the more stuff you have running in your vehicle , the higher the rpm's are supposed to runn . so far mine has not ran above 1200 . hope this helps .

I think with the manny you would need to have the e-brake on for it to work also. but i couldnt say for sure

Just checking to make sure you know you have to have the parking brake set and your foot off of brake. Mine also takes a few(maybe 10) seconds to kick in.
