Ugh, found some clues.... it is looking like something much more mundane.
It looks like the wire just scoots behind the center console and under the carpet; got the kick panel off and found a nest of hanging wires.
This immediately freaked me out and I went back the interwebs to look for some references.
I guess these are the aux switches....hanging wires here and in the engine bay just north of the firewall; ok. Haven't been back in there to find the mystery button leads and pin out on the ECU.
The aux switches have been on my todo list; so found that info here:

If anybody reads this far and knows; so the switches; two 30As, 15A, and a 10A. I am assuming these have associated fuses and relays; If you want to convert the remaining two channels [15A and 10A] to 30A can you just swap in 30A fuses and relays if needed[I am assuming these are somewhere in one of the OEM fuse boxes][haven't found those yet].
When I originally heard about the AUX switches I thought for sure these were some kind of trick distribution box setup like you see in the aftermarket; I am a little surprised they are just thrown in with the factory loom.
Ok on to the other clues; this is what I was afraid of; something goofey, i was hoping it was some interface to a power programming piggy back controller or something.
So during my bonding time with the under chassis I remember seeing this random wire floating back around by the passenger side frame rail.
Looks like the bro before me; had some old school hot rod rigging going on. More evidence this bad boy was a mall crawler; at least it was most certainly not jumped or possibly even off-roaded before me. It's got 35x12 ET 44s on it. Rubs on steep driveways; it looks sick though. I am heading out to Austin tomorrow to get a stock exhaust. and then I will BOLO for some little 17x8.5 ET34s . Haha this thing has a tiny Flowmaster 40 on it; it's obnoxious.
I am going to do a little research if I can trim down all the pinch welds and what not to make it flex, but I am thinking I will find that these tires will impact the upper outside fender at full sag. I'm not sure if I am motivated enough to pull out the strut; hopefully I'll find some posts on it or something[20x12ET44].
So, I'm guessing once I get the wire's traced and pinned out it's going to be some kind of EFI spark cut at the ECU. Which kind of makes sense that it would just cut the engine at idle, probably meant to flood gas while rolling and then pop off a spark for those flames. I used to love doing that in the hood with my carbed out two wheeler back in Florida. Not really looking for those kind of shenanigans with my little new-to-me go fast truck here. I wholely suspect that is what this is; a little bummed; but seems like good news for an easy "offroad" life on this truck up till now.
..you can see the liquid wrench dripping; getting ready for the turn up on those quiet pipes tomorrow.
