Hi Ken,

I'd like to say the EFIS is wireless, but it does employ serial data streams to keep the wiring bulk to a minimum.  I am guessing the couple B models I am comverting now will lose about 25 lbs of wiring, and I'm not kidding!

Admittedly a tough place to take pictures, but I tried to snap a few to give you a feel for the "amount of yellow" visible as you look up into the EFIS installation from below.  Don't show these to your mechanic unless you plan to buy it!
