I would probably modify a painless wiring harness./the original harness is not equiped to run guages.The correct harness is available from MG Magic but it is a little pricey.Somewhere around $500.Then again,a couple hundred for a harness to modify,a bunch of work,it might not seem so high when you can just match the codes on the wires to the manuel.I just redid an old one and all the code tags were still on the wires.I just put it together according to the book.Nothing to it.You just have to be able to read and count to ten.
