Little help with these connectors?? Pic inside

I believe I am right with these wires but just want to make sure.

Little grey connector Pink- Power
Pink/Blk Ign Power
Brown Cooling fan relay from HVAC controls

On the Black connectors I only need a few wires here.
Red/Blk Fuel Pump?? If I apply power here will it energize the pump?
Purple- Power for TCC solenoid that goes through the brake switch?
Tan/Blk TCC ground???

To wire back up the TCC would I connect the Purple and Tan/Blk to those connectors and then use the dark green as a ground trigger? Or just connect the purple and use the Tan/blk and ground that?

Sorry for all questions I am almost done my commander 950 install

TCCi s controlled by tan / blk to ground , the 3rd wire is a 4th gear input to the ECM
