LOL, i have also noticed that when removing uneccessary wiring, some of the wiring could be linked to other completely different parts of the electrical system.
For example when you remove the A/C, somehow it is linked and effects the radiator fan and keeps it constatntly on and to cure it, you have to bridge a connection. So this will also be good to know what electrical circuits are working in conjuction with another, what is safe to remove and what is not.
