The automotive industry must use thousands and thousands of different connectors, collectively. I would like to build a catalog of these connectors, referenced by where they are used in each vehicle. I think this may be a large task, but, as far as I can see, there are very useful applications of having these parts available.
To clear up, or specify what I am looking for: I am looking for the connectors found on the harness and control modules, both male and female.
I have mitchell on demand available to me, and that is good for vauge pictures of the connectors and pinouts, but nothing for sourcing replacements.
Knowing that Delphi was part of GM for a long time and has grown to be one of the largest (if not the largest) supplier of OEM controller modules and connecting hardware, I figured that would be an ok place to start.

But I am missing a method to connect the parts to the application.
A search of "OEM connector" on this site led me to another company, ChinaCWB.
But without holding the original part in my hand, and painstakingly matching each one up to the product in each supplier's catalog until I find one that looks like the right one, I don't see a way.
The aftermarket industry has accomplished this with radio connectors. I'm looking to do this with many other connectors, ones that could be used to tap into signals used in car alarms and other interfacings: harness to harness, harness to module, harness to sensor, harness to fuse panel.

Does anyone have any ideas how to accomplish this, or know of a good resource?
