Wiring Diagram Info Needed.

If anyone out there has a (2011 Coupe) wiring diagram, I would appreciate it if you could do a little minor research for me re: three connections.
1. On the FSCM, which wire is a switched power wire that is not the PWM for the fuel pump?
(reading the ‘net suggests it’s pink…. but I’d like more confidence?

2. Differential temperature sensor: where do
those two wires go? The main ECU or a body module or where? I need to pick those two wires up at whatever module they run to as I am going to repurpose them .

3. On the connector to the throttle body: which wires are the switched ignition power and the ground?

Thanks to whomever can provide this info.

Also, if there’s a source to buy the diagram, let me know?

Hello.
Not on the site much.
I have factory maintenance manuals.
As soon as I figure out how to post images---I'll send you the page that has the throttle body connector image.
From what I have read so far:
Supply voltage is on the GRAY wire.
Ground is provided by the TAN wire.
Mechanical engineer--so my reading of schematics is sometimes limited.
Working on the images---ASAP.

Found the schematic----on 3 separate pages of the manual.
Working on #1 and #2 above.
Hope this helps.

The schematic for the diff temp circuit is below.
