Hi Zedn,
yes, I needed the 12V pull-up on both speedo and tacho. I will be honest and say I do not understand exactly what that does to help, but I wired per the instructions and they both work.

The manual is not real clear on the zero reading for the speedo until calibration. (Actually it does not say that at all.) The tacho worked right off, but I did have to select the correct pulse/rev for it to read right. It still read however before I did the selection.
