Transmission wiring harness diagram

Hi all.
New member.
Ive been scrolling and cant find it. Ive downloaded a 771 page wireing diagram for my 2014 Tundra. Unfortunately, i cant find one for the transmission solenoids and temp sensors. Im chasing a broken wire in the #1 temp sensor. I just installed the transmission used last week. The CEL is on and TC is off. Ive had it scanned at a shop. Ive scanned it on my pocket scanner, my friend scanned it on his Snap- On" Zues". Everything we do leads us back to a break in the curcuit. Ive swapped the internal harness over from my old transmission to the new with the exact same results.
Im having issues chasing the wires into the external wire harness due to the internal wires at the plug are in a sealed non tamper block in a round pattern that goes to an 8 and 7 row double row plug block.
Any help is appreciated.
Sorry about the grammar.
Im exhausted.
