I apologize if this was posted elsewhere but I'm having a hard time finding anything at all. I just dropped my new engine in and of course I didn't lable one of the wires coming from the starter to the alternator. It is a small y/r wire with a single connector (circled in red in picture) and I cannot for the life of me figure out where it's supposed to be plugged in if anywhere. Any help is greatly appreciated. Thanks!

 

goes to the oil pressure sensor just to the left of the wire

 

Oh god I feel like an idiot🤦‍♂️ thanks a million
