Anyone know the wire codes in the electronic mirror on the 2017 Edge Titanium? 
  
I'm waiting for a Mirror Tap to arrive so I could install my Escort Passport 8500 radar detector (I'm trying to rid the annoying wire dangling in view) .  The mirror when unplugged appears to have 3 blue (one striped) , a gray and one other color. I need to determine the hot and the ground. 
  
I think the Mirror Tap will have 2 wires.  One hot (red) and one ground (black).  I would like to hook into so I would have power which would turn off/on automatically with my ignition. 
  
Hope I posted this correctly as it's my first time on this forum. 
  
Thanks, in advance.
