Hello all. Can anyone point me in the right direction?

I want to locate the dome light negative wire without having to run a wire from the dome light unit itself. How can I access it from either engine compartment or under the dash?

Any pointers are much appreciated.

why? Much easier to answer that way.. or you go get the wiring diagrams from erwin.

Why? I'm fitting an alarm that works off the dome light.

ID the fuse and trace from there? Fuses are behind the glovebox.

Blue/grey wire to pin 67 of BCM, I think.

Thank you so much pist0 and Wino.I really appreciate your feedback!!
