I'm thinking of a project... but i need to verify/know some items.
patulong naman mga tsikot gurus on car electric wirings?

1.) common ba yung wiring color coding for all cars? like for example, RED for 12V supply , BROWN for ground & white-red for starter, & so on? tama ba yun?
2.) on the ignition key, it has ACC, ON, START..
2.2.) What is the color of ACC? ON? START?
2.1.) going to common ground ba sila? or common 12V?
2.3.) what size of wire ginagamit sa ACC? ON? START?
2.4.) my common ba ang ACC & ON?
3.) about computer box, will i still start the engine even its 12V supply was cut-off? where can i find the fuse of the computer box?
4.) where can i get electrical wiring diagram for isuzu trooper & toyota revo?

eto lang muna... tnx for those who will reply...
