Add Me to the 4X4 Swap Club. Now I need a speedo

Exactly. Auto is electric controlled. Shift motor or control track.

Manual is just that, nothing electrical about it.

Ditto, the manual 4406 has shift levers in the front side to control it.

The TOD 4406 has both a shift motor to control gear ranges and neutral, plus a single wire(the brown wire) to engage the front drive shaft. So you can't do much with just the one wire alone and ignore the shift motor. If you get it into 4WD high, which is the normal position, you could then control the application of the front drive, with the one wire and a switch.

This explains how TOD works. I would think you could wire in a lead and actuate the TOD while driving.

Why not a simple GPS speedo?
Looks like an $80ish fix!

Except it doesn’t address the signal needing to go to the PCM.

I wonder if one could fake it, like when we used to install aftermarket
cruise control systems. The "pick-up" was put close to a weight on
the drive shaft.

With some of the after market systems, they do about the same thing.
Convert one "pip" to whatever you want. An in-Line Speedometer Calibrator Module
is what I am thinking....

I’d think it’d be just easier to add in a factory one. If you started with the appropriate case it’d be plug and play.
