Dumb Question: PTO VREF
OK so I've read on here that the PTO VREF wire is a 5v source and that what I need to wire my pressure sensors to for my fuel and coolant pressure. My stupid question is, when I find this wire, does it already have the 5V power going to it or does it need connected to something on the cab side of the firewall? I assume I will find it in the bundle of upfitter wires hanging on my firewall on the drivers side?

OOPS I was WRONG it is the Vref 5v
There is a Vref in the passenger compartment near the parking brake along with the PTO and BCP.
if you need a VRef that value will be 5v.
You can pull that off the IPR,EBP or a few
other places in the engine bay.
Have a look at this engine control PDF for
the VRef locations that you could tap into.
Watch out for loading. You don't want to pull
it down too far or you will have problems.
I thought that I had the high idle stuff but
right not can't find it. It has the PTO info.
I will post it when I find it.
Found the PTO and BCP connection info.
