i can't help with a wiring diagram, but i can give a guess for troubleshooting advice. the gauge cluster signals for speed, rpm, coolant temperature and fuel level, are all delivered on the same CAN communication wires.

if any one of these parameters still displays properly, then i expect the problem is internal to the gauge cluster

This is an old thread but since it started up again, I'll throw in my two cents....

A few years ago, my Speedo in my 05 Elise stopped working intermittently. I found that if I hit it, it would started working again. Seemed to me to be either a loose connection or bad contacts.

I pulled the instrument cluster out, reseated the connectors and tried that. Didn't work. Ended up taking the back cover of the instrument cluster off, taking a soldering iron to all the solder points on the circuit board I could reach to reflow all the solder. Put it all back together and it's been working ever since. Just a bad solder connection.

I fixed a buddy's old 87 911 the same way a while back. His car was intermittently stumbling and running rough. I pulled it his ECU and reflowed all the solder connections and fixed it. Dealer said it needed a new ECU.

Might not be your problem but it's worth a shot
