FlyONSPEED.org  Reduce Loss of Control Risk

I plan to use the test harness drawing to wire the unit into my aircraft, is this the latest drawing for this purpose? Will the unit perform without the EFIS serial and OAT connected? What features do I give up without these connections? At one time I saw a screen shot of the WIFI interface and setup parameter page but I have been unable to find it again, please point it out if it is available. Thank you, Don Pansier RV7
