Just an FYI, if anyone needs what seems to be unobtanium anymore, a repair pigtail for an a/c vehicle blower resistor, Standard S630 pigtail happens to fit.
Whats its original application you ask? 1981-2011 Ford's of various models with manual HVAC controls.
Now, thanks to messed up catalogs, even this thing can be hard to find depending on what year and vehicle you are using to look it up. 1996 Crown Victoria happens to be currently in the books with the correct listings. For my 1989 Ford it did not (incorrect listing for everything from 86-90 for that matter). Took some digging to find the correct p/n for the ford, but having gotten intimate with its details, is why I tried it for the GM and we have success without resorting to individual spades.
