Mystery plug on harness
 

I'm not entirely sure that I know what this connector goes to. It's sprouting out of my wiring harness and when I pulled the motor I seem to remember disconnecting this but now that I'm putting it all back together I have no idea where it goes. Help?

It's a yellow wire with a female push connector kinda like a butt splice.. Passenger side by the oil filler neck.

pics would help

Female bullet connector would be for the coolant temp sensor.

A flat slide on connector would be for the oil pressure sender.

yeah I finally found it. Coolant temp sender. Thanks guys!
