After a year of searching, the end result was SO easy....
I am using the Prodigy Controller:

The prewired adapter is 13 bucks (beleive it or not):

The install takes 10 minutes and is a simple plug in.....
Here are the instruction I got from the Land Cruiser site- I BOLDED how I did it- SO EASY!
What I did instead is take all the panels off. Start by removing the horizontal plastic
bezel above the steering wheel, the one that has the light dimmer in. It comes right out by pulling on it. Then (or first, I forgot, check), remove the circular trim around the
ignition key slot (careful, you must turn it and pull to remove it, there are tabs that have
to be aligned with slots). It should then be possible to remove the entire lower plastic panel (in front of the driver shins and knees). To do this, remove the single black screw
on the very left edge, close to the door. Then remove the 4 screws holding the 2 handles
for the hood and gas door. The lower plastic panel can then be removed by pulling gently,
there are 4 or 5 clips holding it, all around. There will be several switches and harnesses
into it. Watch out for the skinny one on the right, those wires are small. You can disconnect all the harnesses and remove the panel. Next comes the metal knee brace. It's
held by 4 or 5 bolts and comes right off. After that you will clearly see the black plastic
vent I mentioned earlier and maybe even the connector, in front or above it. If you don't
see the connector, remove the vent conduit as described above and the connector should be visible. Again, connect your pigtail (see below) and put it all back together after checking for voltage.
Now, to take advantage of this connector you'd want to plug something in. The brake adapter I listed above was a PRE-MADE to connect from the Prodigy Controller to the "Toyota" white plug.
Buy a good brake controller (I got the Tekonsha Prodigy, a late generation solid state gizmo that is supposed to be top of their line and perhaps the best out there). .....
