Does anyone happen to have a pinout for the connector at the back of the guage cluster? I'm planning to design my own digital cluster using a microcomputer and a lcd screen and I was wondering if I could tap into the odb2 and 12v power from that connector. I want it to sorta be a drop in replacement.

The 2000-2001 Bonneville used a printed circuit ribbon harness for the cluster/radio/hvac controls. You will have a really hard time tapping into it.

However, the cluster doesn't receive OBD2 data like you are thinking, they are all individual signals from the PCM. You'd need to tap into the OBD2 port to get that data.
