The big transmission control unit connector can be tucked inside the ecu compartment. Then the other auto transmission cables can be wrapped up and zip tied down near the side of the block.

I've been running the getrag behind my M52 since the swap two years ago.

Is there a write up somewhere on how to connect the reverse lights and build the new plug into the harness?

The one thing I am not confident in is electrical work. If I have a step by step I can do it but reading wire diagrams is not my strong point.

Will I need to have the Transmission control unit need to be in the car at all since my Ti is a manual?
