Jason I have a Comanche and nav light at top also. Would probably take you 30 minutes or so to install, if your wiring is long enough. If it isn’t it can be a pain to extend. At least on mine it was. Because of that it still only took approx 1-11/2 hours including paperwork and programming. Don’t let someone stick you because an idiot could do it. Unfortunately you need to know an IA to sign the 337. Works great.
