This is a winter project, any day now up north here?

Does any have information or links to Re-Flashing an LT1 PCM on the bench? I have bench.

I've done it in my car with WinFlash. Made adjustments to Bin in TunerPro. Reflashed through ALDL port.
Got a couple spares in case I brick one, also check charging system on car, batterey voltage car off, load test and if all is well I leave a small batterey tender on the batterey. Instructions say no chargers but this is a tiny charge to keep topped off on like a harley in storage. That what I bought it for 15 years ago. I also start reading and flasing with full charged laptop batterey. No charger! Done mine 5 times now with no issues!

Would it be as simple as running ALDL lines and power lines to the PCM? Probably be nice to get some PCM pigtails, but so few wires and I think you only use 2 plugs? I have wiring diagrams for all if I have not added them to the library.
