Ran the wires into the cab, had to cut the factory wiring opening a bit larger. I will likely use one of these split seals.
Chugging my way through details of the wiring
I made brackets that will attach to the steering colum bracket mounts, one for a fuse and relay box, and another for the drive-by-wire module.
Also added the OBD2 port, accessible but tucked out of the way.
