Based on that 1 picture, there is not much we can say, other then that the clams are off.
I would suggest you get your camera out and start taking detailed pictures, and upload them to https://imgur.com
We can then take it up from there, and answer your questions, and deal with comments step by step.
On the facebook page you mention you're looking for "stray wiring, and reference of what things should look like".
The more pictures and questions you post, the more input you will get here.
As for your homework, here is:
The Electronic Parts Catalogue.
The Technical Information System
The Opel Academie guide (in Dutch)
The owners manual
