Chat Agents were courteous and responsive, arranging for return and exchange of problem item in a professional way.
On the other hand, the part I originally ordered had been discontinued and was replaced with a new substitute. The locations of the pins were different, causing me to install it incorrectly. Luckily it did not cause major damage to anything or injury to anybody. I suggest a well-written instruction manual (not the amateurish YouTube video that lacks specific details) should be made available.
