4L60E wiring question 72 K10 LQ4

After much thought and good comments from members I decided not to install the 700R4 and switch my transmission to a 4L60E..so I traded the transmission I had for a rebuilt 4L60E and have installed in my 72 K10 with a np205 transfer case.
Both are 27 spline. I repinned my own harness a few years back and removed the transmission control wires..so I have made a new harness for the trans and connected it as this per these drawings..

The question I have is where does the pink connector E (round plug) get it's power from? Pin 75 blue on ecm... Or do I have to add a splice to it to give it key-on power?

I don't think I need the neutral switch(C2) as the truck already has a working one in the column, and is wired as such. (truck was running a TH350 for last few years)
Thanks
