Default LB7 previous allison, now 4l80e wiring

Was curious if anyone could help me out with the wiring for the 4l80e...

I have removed the TCM and already know that the tuner will send me a Manual ECM tune when needed. I was wondering since I removed the TCM if I can also remove all the wiring that goes to the ECM as well. Trying to clean up the engine bay and wiring. The transmission has a full manual valve body (Black Box for now).

Tow Rig: 2002 CCSB LB7, Airdog and tow tune.
