I tried getting my wire through that grommet for over an hour. Finally I lost my temper (which rarely happens), grabbed the drill, and made my own hole through the firewall. Ended up narrowly missing a wire loom. What is the secret to getting it through? I even tried a small copper wire and it only went in a little less than an inch and then it stopped up. Is it possible that some cars (2000) dont allow for this?
