91 Z28 tpi wiring harness

I have a 91 Z28 that was a 305 TPI. I bought the car as a roller. the entire harness in the engine compartment was removed all the way to the DS firewall and into the passenger compartment were the ECM used to be. I have the harness with all connections.(I think) My question is can the ECM/TPI harness be separated from the rest of the harness without "hacking it up" . I'm going with a carb and read that everything on the Passenger side can go bye-bye.

Yes, they come apart without a bunch of hacking.

What transmission will you be using?

T56. It looks like the harness has already been "modified" by the previous owner. I may have to do some cutting.
