I thought I'd repost the pertinent info from my original posts in this thread, seeing as they'd been lost in the ether.
First up, a pic of the back of a 4th-gen cluster, with colored circles indicating which color LED goes where:

Notes:
1. Fairly easy upgrade, as long as you don't mind removing most of your bodywork.
2. Polarity is important (both bulb-in-socket and socket-in-cluster)! Make sure ALL your LEDs work BEFORE you button up.
3. The 4-LED lights are BRIGHT! Upon reflection, one would do well just to use the 1-LED versions throughout and it would look just fine (and save a few bucks). The upside is that I can read a map (or a book!) by my neutral light now.
4. The low fuel light does not go out completely when replaced by an LED; it merely dims halfway (estimated), then goes full bright if fuel gets low.
