There is a write up on it..@ work so I do not have the link here, but it describes how to do it in detail. If you know how to wire, then its not that bad. I was trying to do this, but the cluster regulator kept blowing on me. I finally just went with a cluster from Haneline.
Truthfully though, I wish I would have gotten the cluster panel I found online, and just built my own. I truly do not like the way Haneline did their Tac, and Speedo. But oh well you live and learn. It does not look bad though, but I just do not like the style of them.
I will see if I still have that link on my home system and post here if no one else does when I get home.
