Product review (5 stars): ... this by myself in 5 minutes and it works great. Unplug the fridge
I installed this by myself in 5 minutes and it works great.  Unplug the fridge, remove two 1/4" bolts, unplug the wiring harness, plug in the new icemaker's wiring harness, put the two 1/4" bolts in, plug in the fridge.  WAIT a little while for it to start working.  It does not start up immediately, I think there is some kind of timer on the water supply.  It works perfectly and was an exact replacement of the original.
