Hooked up the dome light today. My bride and I went to dinner at a friend's the other night and the dome light wouldn't work. Hmmm.. Checked the bulb. Good. Checked for power- no power. Traced the wire down to the fuse box and found a nice clean cut off wire labeled "CRTSY". Doh! I never got around to connecting it to power.
At least it wasn't something critical like a brake line!
