Product review (4 stars): A little tricky!
This was listed as a replacement for the analog unit in a blind friends Bunn coffee maker.  Would have been nice to have complete instructions.  Had to go home and get on internet to get them.  Went back out to install it and found the instructions erroneous.  Wire colors did not match.  The unit looked original wires and all.  Spent some time figuring it out and it works.
