FIXED... Won't start, no gear indicator light..?

[mam4.6]

No TRANSFAILSAFE...

Problem, folks... Need some help. Driving along the other day, transmission didn't seem to want to shift correctly. I pulled over and turned off the engine. Went to start and... ...nothing. Light in the dash all come on, but no click from the starter, starter doesn't turn over, no sound from the engine bay, nothing. Noticed the light in the cluster that indicates what position the gearshift is in disappeared. My first thot was gear position switch/sensor. Remember the thread??

Took a look, sure enough, the wires had separated further to the point of barely hanging together. Ordered a new OEM sensor/switch, installed it this afternoon, no dice. Still nothing. Do I need to clear the memory somehow? I noticed while i was underneath, I heard a very faint car alarm/siren sound. not the horn-alarm type, but the siren-alarm type. Thought maybe something outside somewhere, but no, I can't hear it from top-side of the engine bay, only flat on my back, close to the bottom of the engine bay. EWS related? Maybe? Everything lights up on the dash as normal, but nothing when i turn the key further.

Any help and suggestions are greatly appreciated...
