To Leo Paugh;,, thank you. I checked the local Buick dealership in town on just a hunch that they might have a standard parts catalog. They've been there since the 30's or so and they actually had a 1992 version of the standard parts catalog. Not only that but they also had the AC/Delco pigtail catalog you advised me about. The counter guys there were very nice and let me sift through the catalogs. They seemed kinda' happy to see a customer actually come into the parts dept. It was sort of like going back in time when you could walk into an auto parts store and the people who worked there were the same people who worked there last week and last year and even ten years before that.
Oh well, I looked at all the available GM connectors, housings, electrical accessories, etc., and I only found one of the two connectors I need. They list the three-way connector as part no. PT 572. The other connector resembles an 'L' shape and is also a three-way connector. It's no longer available so I'll either have to find a suitable survivor in a junk yard or just do without. Being that this connector is under the dash and not the hood I suppose using the spade terminals covered with heat shrink will work just fine.
Thanks again,
Louie Hammel
