Product review (5 stars): Simple, universal,  THANK YOU SUPCO!
Bought this to replace a relay on a mint condition 1943 Hotpoint refrigerator.  I had called every appliance repair place in 3 counties to do the job and none wanted to be bothered.  They just said "you can't buy parts for old refrigerators."  Their loss, because I was able to fix the refrigerator quickly and easily with this inexpensive and UNIVERSAL part.  Installation was easy once I was able to identify which wire was which on the refrigerator (for light, thermostat, fan and compressor), which wasn't that hard, through process of elimination.
Glad I found this part!  (I used the SUPCO website to determine the right universal relay model for the amp demand as labeled on my refrigerator compressor).
