You could probably find them using your favorite internet search engine. I'm more of a numbers guy so I search by part number.
GM Standard Parts Catalog might help. This page shows a 6-way connector with part number 12101916. You can get started with that. Previous page shows the 5-way at 12101915.
GM Parts and Illustration Manuals are structured such that typically the Group for fasteners and connectors are located just after the Group for a particular piece of trim or switch etc. So if nothing comes up with an internet word search maybe by the numbers would work.
ya the problem is they don't fit the 1987 olds cutlass.one thing I've learn is just because the initial search pops as it fits, once you put in the make, model and year it say it doesn't fit the cutlass. a lot of the
g body parts are made for monte carols and Buicks with the possibility of fitting the cutlass.
