Finding the right pigtail
 

I came across AC Delco TechConnect Wiring Sockets and Pigtails while looking for a new blower motor plug.

Just tell them if it's a GM car, what type of plug it is, and how many connectors it has, and it'll return a list of pictures and part numbers.

A very useful resource, in my opinion, to verify that the thingy on RockAuto is the correct one. If you ever destroy a connector, this is what you need. :thumbup2
