Oil Temp sensor wiring harness issues

OilLeaks

**UPDATE**
So I figured out the problem. I swapped the ECU & still got the same high oil temp reading even though I got the proper readings of 5v on the green wire and 0v on the black wire. I decided to do a little more investigation. As it turns out, there was no continuity in the black wire. I replaced that wire and everything started working again. I guess when the previous owner did a repair he didn't do it properly. Apparently, the ECU will default to a high temp reading if the sensor isn't working. I doubt anyone else will have the same problem, but if they do, hope this helps!!
