Yeah, it's relatively easy to get to the bolt except for the wire loom clamp. That thing is a PITA. Once you have that free it's two nuts and you can remove the fuse box to access the 12+ bolt.
I've checked my diagrams and I think all I need to do to get the dash indicator working is put a jumper across the driver's side headlight connector. I need to see if I have the correct size StaKons, if not I'll try to get that done tomorrow and report back.
