I would like to install a new combination speedo and tach (part#709000702) on my 06 Heritage. They only sell them for Softails as old as 2008. I'm guessing the fitment issue would be the factory plug arrangement. I am not worried about the plug and play aspect, so I could wire direct from the harness bypassing the plug if I knew what wires were what on the bike and the speedo. Can anybody help me here? Perhaps a wiring diagram or simple drawing showing wire colors and what to connect. I realize that some of the functions won't work, an example being the lack of gear shift sender and such. I just love the way they look and all the color choices. I have looked at other aftermarket combos, but nothing pulls my trigger like this one. Any response would be appreciated.
