I would like to install a MMB tachometer ( Link here )in my 2006 EFI Night Train and would like to know if someone has already done it. Does it need to be wired in the coil or can I use the green connector that is supposed to be under the dash of my bike? Is it necessary to install anything else to make it work correctly or just the way it come out of the box? If someone knows anything more about this equipment, please give some informaton about. Thanks to all and have a nice ride.
