Product review (5 stars): Fortunately I was able to reach under the dw parts ...
Unfortunately I didn't purchase this part through Amazon.  Wished I did now.  I could've saved about $15.  Oh well.
I just wanted to let others know that I didn't have to remove my dishwasher from the cabinet.  Fortunately I was able to reach under the dw parts and disconnect the wires & nuts by feeling the applicable parts.  I strongly suggest using a 3/4" deep well socket and a ratchet. the entire job took about 30 min, including verifying the old element was bad and the new was good prior to installing. Remember to shut of electrical power at the circuit breaker.  No need to shut off water supply or disconnect drain hose, etc..
