help hooking up new tachometer gauge please help
i bought a new gauge and gotta everything hooked up but the rpm gauge. Now i have installed a koso on a yamaha i had however i cant remember how i did it heres what the china man sent me for info.
RMP:you can connect it to trigger coil（Blue & White wire）,this is more good,signal is more stabilize;or primary Ignition(Black&Yellow wire);Guage RMP signal wire:Black &Yellow.
so my question is when he says trigger coil any guess on is that the main coil or trigger off of stator. And primary ignition to me is coil pack. Can anyone help me out a little before i wire the gauge up and ruin it.
