I'm trying to find an pto control switch kit to put in a Freightliner M2 to control rpms for pto operation.
We installed a pto and feed bed to a truck, but newer freightliner requires the additional rpm switch installed to go past the 800rpm idle bump up using the cruise controls.
Called our local dealer and they gave me the number for their district's pto parts guy at another dealer, but i've called multiple times, left voicemails, and emailed him with no response. It's coming up on two weeks and need to find these parts for my customer.

@devedo do you have an M2 spec'd with the PTO configuration you need? You're going to need more than just a switch and PTO to get the desired feature to function...
Copying a configuration of a similarly spec'd truck is the easiest thing to do without having to do a CWO.

@RocketyMan is the freightliner body builder software part of DiagnosticLink? If it is I'm guessing our licensing isn't upgraded for that portion of it. I've changed the parameters in the CPC and MCM for PTO control and changed any rpm limiters to 1500, but still have the 800ish rpm limit.
I attached a pic of our Diagnostic Link screen adn the BHM on left side doesn't show availability for changes like the other three that lit up.
This is only the 2nd Freightliner we've done a build with that required a higher rpm limit and the first was at least 2yrs ago so all my programming experience is with Internationals and had to do the training classes for my licensing for Diamond Logic. -
@devedo So that's a good point with Diamond Logic and Internationals. DTNA uses the CHEC tool which is synonymous to Diamond logic...or similar.
Have you done the CHEC tool ARC training. If you want specific logic for PTOs and such, this is how it is done.
BTW, in your screen shot, you need to uncheck the "Enable automatic connection of SAE standard J1708 and J1939 devices" in the options part of DLink. Then you can connect to the BHM (BulkHead Module) properly.devedo Thanks this. -
