Thanks for the info!
That begs a question Why the extra $2500 more to for dual Pmag?
1) Auto harness is much less expensive
2) Auto plugs and adapters are less than regular plugs
3) Sick vs Pmag units are similar in cost
Pmag setup is less than Slick. Only thing I can figure is Lycoming gives an egregiously low credit for the slick mags and harness. If anything it should be less to outfit with Pmag not more.
