06 Tacoma Prerunner Rear Diff ECU wire location?

Hey guys, I'm new so please forgive any dumb questions.
I was doing some deep cleaning on the dash and found the wires plugged into the top blank plugs. I'm pretty sure they are the fog lights, rear diff lock, power invertor for the bed,
I'm not sure about the one wrapped in white tape.
My questions are... If I have the plug for the RDL switch, then I must have the plug for the 4x4 ECU, correct?
If so... Would anyone know were its hidden? I know it would be behind the glove box/airbag but I cant seem to find it.

 

Pics and location are here.

Thank you, I've been digging through that one for a few days now, lol.
I'm thinking the wire/wires are tucked away or tapped up somewhere that I'm not noticing.
Or... Maybe the wire just looks different since its just the RDL and doesn't have the 4WD.
I wonder if the ECU is different for the trucks that don't have 4WD but only have the RDL.
I'm hoping to find a junk truck in my area that I can compare to.

I found this wire but its different from the 2 in the other thread, I think it goes to something else but I could be 100% wrong.

 

There's 3 different 4wd ECUs on 2nd gens depending on the configuration

2wd with locker
4wd without locker
4wd with locker

Not sure how much of the wiring would be there as far as adding the locker.

 

Thank you, I wasn't sure about that.

 

AWESOME! Thank you, that is really helpful.

 

Oh and your mystery connector is for Auto LSD, only used on trucks with VSC/traction control which was a pretty rare option on pre-09 trucks.

 

Oh?

 

Was referring to this one.

 

Gotcha, I wonder if the locking differential switch connector might be hidden/tapped up to harness also.

 

From what I understand the sub harness for the actuator isn't there but I can't remember if it's just the part from BD1 or all the way from ID1.
