I just replaced the engine in a 96 blazer with a 4.3L vortec engine (Vin code W). I am starting to hook all of the wires back up and it looks like I forgot to label one of them and I am not sure where it is supposed to go. It looks like it wants to go toward the alternator but I want to double check to make sure I do not short anything.

Thanks for the help.

 

Goes to the back of you alternator.
