this connector going to one of connectors under passenger side dashboard just below tweeter cover. remove glovebox and you will find them. There is few of them but all are different from each other. You will be able to mach it according to size.

This are diodes rectifiers. Don't do anything with them. Wires green/red and green/blue are signals from door switches. I think diodes have something to do with connectors 4 and 7.
I wouldn't also bother about 4 and 7. After you install it in your car you can disconnect them to see what will happened. IMHO they are for connecting other option harness or other configurations for different car maybe. I'm only guesing so I may be wrong.
6 have to be connected to constant +12V from underdash fuse box. And 5 is directly connected with 6 in case you wanna use another option harness which need constant +12V so if you don't have any leave it alone.
You can sell it to me then I will fully test it and post results here
