92 gauge cluster to 94-96 cluster

I'm just wondering how hard it is to convert my speedo cluster to the 94-96 cluster. The reason being the digital odometer. It obviously looks better. I know there is some wiring work to be done. Is it Just splicing wires and connecting them to different ones, or is it more involved. I have always kind of wanted to this but now I'm told that you can't make the green lights blue in mine without alot of work. So if it's not too hard I'd rather just convert to the digital odometer. I have seen it discused before, I'm just not sure which forum it was in.

Also is it possible to have a honda dealer change the millage on it or do I have to get one with a few thousand more miles than mine and switch it out once it gets to that point. Which would be hard because you can't really know where it's at unless it's on and it can't be on unless I convert all the wires and crap.

Thanks for any help,
Nick
