I am installing a FlyEFII System 32 in my Glastar. I completely removed the old EFII legacy system, as this newer system is much more 'plug and play'. Yet I am unsure where to route the tach line to on my Skyview. It says to attach to the RPM input ... where is this located? (And I assume attaching to one unit will transfer the same info to the copilots side). Thanks.
