Just saw this now. Not sure if you are still looking for the pinout but thought i'd reply.

I've done some extensive work on the speedo and a lot of reverse engineering as i'm currently swapping out my second gen cluster with the LFA style 3rd gen cluster. Diagram and pinout of the 2nd gen cluster below. Hope it helps.

What irritates me is the differences in positions of my wires of my connection plugs. Maybe also the colors differ, but I don't find any XE20 wiring diagrams. Can we anyhow confirm what's wrong or right? I'd love to see wiring diagrams from 2ng gen IS without being forced to login on websites where I have to purchase any?

As for me, I want to run a 2nd gen cluster in my 1st gen Altezza.

Thanks in advance
