Nothing wrong with this one, but I ordered the wrong one initially.Be sure you're engine temp sensor has 2 prongs and not one.There are 2 common types. For older models (specifically 5.7 Liter Indmar, 1996 EFI), the other one can be found  here:https://www.amazon.com/gp/product/B00027GZ7I/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
