I am going to create a list of popular Aptiv (formerly known as Delphi) connectors since GM sensors are popular in the aftermarket world, at least here in the US. The nice thing about Aptiv connectors is you can buy them on Mouser for just a couple dollars each.
This page is a work in progress, I would like to add photos of each connector and finish the list I have. If you have any requests for GM/Aptiv connectors just ask, I will add it to the list.

Re: GM/Aptiv (Delphi) Connectors
Currently testing with a 4 bar map sensor.
Part number: 12643955
This sensor is only $19 from rockauto, or $27 from amazon. Much cheaper and readily available compared to many other MAP sensors.
According to sloppy mechanics themselves this is the Vout vs PSI response.
