So recently my rearview mirror came off and I didn't have anything to stick it back to the window so I cut the wires so it wouldn't smack the windshield but now I got the abs light and airbag light with a p0500 code for a vacuum leak. I tried splicing them back together but now it seems like my battery got fried because it kept dying out every few feet. I'd really like to know what wires those were and what the hell is going on with it if anyone's done the same thing by chance....
