ok got the pinouts, looking at the back of the cluster pin 1 being top left, pin 20 being bottom right.

Pin 6 is Ground
Pin 12 is Serial Data
Pin 19 is Power +12v IGN
Pin 20 is Power +12v

When i power the cluster up on the bench it beeps and displays the X for fault codes logged. So i sent F2,56,0A,AE to see if it would do anything and the fault indicator X went off and cluster flashed like it reset so is happy with that!

I made one for a mate a few years ago.....he wanted it to be set to the current (failed) speedo reading. it took about 28 hours to complete though.
I used a pic micro for the job.....some quick maths (very quick) and worked out roughly how many pulses were needed to get it right and set a "for next" loop. So my math was a little off, about 6000 km off but another 15 or 20 mins and the job was done.

I havent tried this on a VT cluster though.

Not sure but i think someone tried that and when you hit 999,999 that's it. Could be wrong.

No it just goes back to zero and then you can set it with tech 2. This is only needed for vx series 2 cluster from memory. All the others can be done via eeprom.

I was given a vt single window cluster and the onboard chips look totally different to the one in the pic would it be of any use to upload a few pics.

I'd take a guess that it is, that's a microwire serial flash IC.
