Need Help with relay/overload on Whirlpool Fridge

The relay/overload switch went out (as told by local Appliance Repairman). So I ordered parts from this site (part #8201786). When the parts came they did not match what we took off the refrigerator. So, I ordered a second box with parts #4387835. Neither box of parts matches what I took off my fridge. I was then told that the original parts where discontinued and these parts where replacing them. Unfortunately, I am not that great at figuring out how to make these new parts work to fit my compressor and get this fridge running again. Any help in trying to figure this out would be greatly appreciated!!

The compressor is EHY 90HLP. If you have a diagram that would be very helpful as well!!

Thanks!!!

The first part, 8201786 came with complete instructions, so I would use that one.It might look different, but must be electrically equivalent to the old one. Rather simple to instal either white plastic box, just plug it into the compressor terminals, then,plug in the refrigerator connector to the socket supplied, and the run capacitor also.
