Need advice on pulling a 5.3

[bigmoe]

I just rolled a wrecked low mileage 2005 GMC Yukon 4wd into my shop to pull the 5.3 that I have sold to a guy. He wants to salvage the engine wiring harness to have it reworked for a swap. Any advice on where to cut it? I found the TAC module for the dbw pedal and will get that and the wiring. I see the ECM and have it loose, Where is the TCM, I don't see it? Should I remove the engine harness before pulling the motor or is it possible to stack it on top, disconnect the o2's and trans and pull the motor that way? I know the upper bell housing bolts can be a ***** and I was thinking about cutting the tunnel to get at them and avoid having to remove the intake. Appreciate any advice.
