Help with electricals

Hi Team, I'm a newbie with a question that u may be able to help me
with. I have a 1998 falcon GLI wagon that is blowing the IGNITION
fuseable link (located in engine bay) when I flick from low beam to
high beam. The only other thing I've noticed is the globe lighting the
auto transmission shift (i.e PRND12) has blown. I'm not sure if this
is relevant but hopeing someone has some knowledge of the electricals
of this car. Otherwise maybe advice on a link to a wiring diagram.
Thanks heaps for your time and help. Regards michael
