Ok, trying to get the wiring sorted out and could use a little help here as well...
Speedometer:
The speedo connector is almost the exact same, I'm pretty sure it will just plug right in, it did in the
Amigo MT swap thread.
4WD:
In the amigo swap thread, John says
[tab=30]
"The speedo and 4wd indicator switches use the same plugs from the auto harness so no wiring needed there. "
Looking at the connectors on the tcase for the 4l30e, it looks like these are the connectors on the harness for the 4wd switch:

Is the sensor the same on the 4l30E Tcase such that I can swap the whole sensor out? Or should I cut off these connectors on the harness and put on a weatherpack connector? I think it's not the same and I have to do the latter, but if the sensor does swap and the leads look in good connection then I'd rather stay with the OEM fit.

Reverse:
This is where I'm unsure of things. In the amigo thread John says:
[tab=30]"Now you will have to cut 4 wires off the mode selector switch to wire up your reverse lights and your clutch safety switch (if you use one). There is a white/green wire and a red/yellow wire, those 2 are for your reverse lights. You can wire them to the reverse switch in any order, the lights will work either way. Then is a black/white and a black/blue wire that are for your neutral safety switch. You can run these wires into the cab and install them on the clutch safety switch on the clutch pedal or you can just wire them together, but doing it this way will allow your truck to be started even if it's in gear and clutch isn't depressed. "
My transmission mode switch seems to have different color combinations.
Here are the transmission mode switch wires on my rig:

And here's a wiring diagram I found for the automatic transmission mode switch:

Anyone have any ideas which wires I should wire up to the reverse switch? (right above the roll of electrical tape in this picture:

It seems like it has some brains to it that takes the pnk/blu, pnk, and blu/blk wires, and determines what position it's in based on what combination of wires is hot. I'm hoping some pair can just be reverse and then blu/blk can be for cruise(more on that below) but if not, then I can get crazy with an arduino and program it to do the right thing...
If anyone knows offhand, please tell me.
Cruise Control:
The donor vehicle did not have cruise control, but mine does, and I'd like to keep it functioning if possible. I do not have the sensor that John shows in his swap thread where he has the opposite situation (donor had cruise, his truck didn't, and he didn't care to keep it). So there is a bolt plugging that hole:

Can I swap positions of that bolt and one of the upshift light switches?
If I do, the wiring seems like it should work out looking at this diagram:

Now my automatic transmission mode switch does look to have a blu/blk lead, to me it looks like the third from the right in my picture of the wires above. But thats only one of the two wires. I assume that the sensor is just a switch, that the other wire besides blu/blk is ground, and that when the switch is in the closed position, it's pulling some pin on the ECM to low to say it's in neutral (or in gear, whichever way it goes)
Is it safe to say I can wire one side of the switch to the blu/blk from the automatic transmission mode switch, and the other side to ground, and that will make the cruise control cancel when the trans goes into neutral?
AT Trans Temperature Sensor:
Is this connector (and its mate on the outgoing 4l30e) for the transmission temperature sensor?

Should I just measure the resistance of the sensor, find a resistor of a similar value, stuff it in the connector and tape it up? Is there a place I could put it on the manual trans and plug it in?
Thank you in advance for your help,
