My Range Rover 2003 L322 recently had the cluster die,

I bought one from a junk yard (new cluster), I've bought a pixel repair ribbon for it from akspeedo.com
My friend has leant me his Tacho Prowhich is in a box full of cables etc i've looked through all the instructions on the cd
and nothing for Range RoverL322 2003 !! arghhh

Anyway the cluster now is in bits and I want to adjust the mileage to match my history before I put it back in the car,

I've found some stuff on x5 and it looks very similar to my instrument cluster, but i cant find any instructions guides for that cluster either?

I thought it would need to be connected to the EEprom, however all the chips on the back have some kind of protected glue or something over it?
I can't find the EEPROM as some of the chips are blank?

Please have anyone used a Tacho Proon the L322 before? If so please can you help me.

I've never used this before so please can you dumb down any advice as before yesterday I'd never opened a cluster or heard of a EEPROM

Thanks
Hyde
