Hey if anyone with knowledge is still even looking at this thread...
First of all, great write-up. I did the swap a couple months ago using it and it worked great. The one thing I don't feel like it covers is the separate oil & volt gauge. My truck doesn't have this but I've got one in the mail that will be here tomorrow. I have no idea how it hooks up. Since my cluster has an idiot light for charge & oil, it seems like the sending unit must connect to both clusters. So does this mini-cluster just connect to my main cluster, or what? If so, where does it connect (which plug number)?
