Want to get a tach for my '06 Superglide and am leaning towards the 4.5 inch or so combo model that sits on the gas tank, P/N 70900070A. H-D used to offer several of the in-tank units for my scoot, but this is the only one available now as far as I know. Have any of you 35th or WG 2006 owners installed this unit? Since this thing fits other years, I don't know if the auto mileage transfer function and the plug and play feature works with the 2006. A number of things are unique just to the '06. Anyone have access to the installation instructions for the gage? That might help me in making a decision too.

Thanks all!
