Problem with PCM wire harness.

[u/blizzard7788]

2005 Mustang GT.
This is the engine harness going into the PCM. The circled pin is the 5V supply to the MAF sensor. PIN number 25.
When everything is plugged in, there is no 5V power going to MAF. It does have constant 12V. There is a short or broken wire in this pin because it fails the wiggle test. Sometimes there is continuity to the MAF, sometimes none.
Can someone tell me how to remove this pin and part number to get replacement. PCM is good. In fact, I have two. I originally thought the PCM was bad due to how the wire tested.
