PDP - Power Distribution Panel ( inside the passenger dash board with relays and breakers).

You will need the Wabco toolbox to talk to the ABS. It's a COTS (commercial off the shelf) system so start with visually checking your sensor cables at the wheels, make sure your truck's voltages are correct (voltage spikes will cause it to go into a safe mode and shut down), and then try to talk to it.

Fuzzy , Found software on internet recommend any version number?

I have 12.9.1. Nothing has changed with the ABS since its production on these specific vehicles so you don't need the latest software.

Here is a photo of the area with some labeling and another of the box the jumper cuts out of the ECM circuit—

Did they stop installing that stuff? I don't have any of that. Just the resistor.

Well that's interesting. Most of the 3126's had them at one point. IDK if perhaps some early or late one's didn't have them. As was mentioned the box is not always shown in the TM's depending on where you are looking. I know it's in the electronic parts manuals for the A1's because I tracked it down to determined it's purpose and the acquisition cost was right at $2,000. Still need to open one up but I suspect it's potted like most engine mounted electronics - would be interesting to know how hard uncle sugar got shafted by whoever supplied them with $3.88 worth of silicone and chemicals for $2k.
