I don't even know why but I am in want of hooking up tach in the wolverine. I also want to out a temp guage. I have no clue how to hook up a tach on these things ... I can do it on a car but this is just beyond my brain power for some reason ... also looking for a small simple plain tach nothing crazy if anyone knows a decent one .. maybe digital info center ... I know they have one for the griz that gives you speed temp air fuel rpm and so on but it is a bit much
