Does any one out there know which wire to hook up to the upfitter switch to get engine up to fast idle on my 08 superduty 6.4l?

I hooked it to the BCPSW
I hooked the upfitter switch #3 to the
INPUT (VPWR)
BCPSW
PCM Pin C1-43 Circuit No. CE926 Wire Color: Purple / Brown
• Applying vehicle battery voltage to this wire begins BCP.
• Engine speed is sent to 900 rpm when all safety enablers are met, regardless of the degree
of battery charge.
• After 900 rpm, BCP regulates engine speed based upon the degree of battery charge, up to 2400 rpm maximum
You also have to set the parking brake to make it rev up.
If you hook to the PTO input it will lock the torque converter. I did not think that would be a good thing for the transmission.

exactly what he said, I did this 2 years ago and it works good, although i used the #4 switch.
