Guys i know your all probably sick of it but i came across a tech docco the other day about the various models of dash clusters and how to swap them around, but i cant find it today for the life of me.

My question is if u go from a base model in a ea(i have it in the XG) to the next level up, with the tacho and oil pressure ect do u need to reset the fuel level gauge or anything? or will it all plug up and be the same?
Also will the tacho and oil pressure sensors be active from the wireing harness or do i need to install them myself?

Once again, Cheers guys.

need to replace the oil sender switch and ad a wire to the loom etc yeah read the tech documents explains it all
