What are folks using to bench tune? Do you buy old harnesses to connect to the pcm?

For GM P01/P59 stuff, yes.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
In my experience most junk yards will cut the engine harness just to pull the engine quickly. That means the PCMs are often still in the car with the connectors attached. These make a great start to a bench harness and are often sold for a very small charge.
yes, i use old connectors to build mine. Eficonnections makes some really quality pieces ready to go
