I'll speak to the shop this morning. I'll hit you up if they can't help me.
Thanks a lot!

I seem to recall you "junkyarding" a connector for your car awhile ago. Was that you?
This is what I'd do - all '88 -'93 W-body GM's used a '730 ECM in a weather-proof case like the Corvette '727. The ECM was mounted in front of the RH strut tower. Go "junkyarding" cut yourself off a couple connectors maybe paying attention and getting one with a BLK/WHT, put your hands on a correct release tool and remove one from the JY donor, remove the terminal in yours, insert the one removed from the JY connector "twist/tape" for diagnostics.
W-bodies = Grand Prix, Lumina, Regal, Cutlass Supreme
Your shop is NOT going to have the correct "gold-plated" weather-proof terminal. I'll betcha!
You want a release tool for a Metric-pack 100 NOT just a generic and you'll have a connector from the JY to experiment with before messing with your ZR-1. There's 22 terminals I believe in each connector so there will be "lots of practice" for you before you even touch your ZR-1.
I haven't actually attempted the swap I just mentioned but I'll betcha' it will be OK.
If you do the JY thing when you're looking if the ECM connector covers are still in the car grab a couple. They're the same as the later C4 Corvette and ZR-1 I believe also.
12031876 is a correct release tool or it's equivalent from somewhere. GOOGLE might be your friend here to find options.

This is what I believe/hope you find in the W-body car under the hood - an easy grab!!!
