2001 Freightliner Columbia, no cruise or jake after trans swap

Have a little issue, replaced to good ol' Meritor electric shift 10 speed to an Eaton 13 speed. Now, as far as I know it supposed to be an easy swap, well, now lets get to the fun part.

This truck has an old N14 Cummins in it, at least what the shops have told me. The issue lies that the cruise does not work, fast idle does not work, nor the jake does not work. Speedometer works just fine. Called around for an ecu reflash to set the parameters to the for the new Eaton and took it to 3 shops. No one can do it. Say its too old don't have the proper stuff. Got to love it.

Now this is where it gets a little confusing. Took the truck to the dealer, they scanned it and told me there is a code in the ecu for it not seeing the electric shift signal, but I got told since the speedo works the cruise, jake, fast idle should be working. Upon that, got told by the technician the ecm is reading that the brake switch is always set. BINGO!!! Also, he mentioned that the parameters are set up properly and that everything looked fine besides that brake switch reading on all the time.

Replace the brake switch, nothing, check the clutch switch, works just fine and no corrosion or anything. Replace the cruise switch, nothing.

As you can tell, I am out of ideas. Any Ideas?

 

Ok, I don't have access to that. So far as I am aware, everything checked fine, even when the dealer scanned the ECU. Said all parameters are good. I will see if I can get that checked.
