ecm pin a12 system ground-what type of terminal for ecm?

I am having a problem with the wiring harness, namely the black wire with the white stripe that is the system ground, pin A12 (this is on a 165 ecm.) I need to know what type of metal terminal it uses, I took ecm down and it was loose, making the car quit if you jiggle the wire. Upon further inspection, this black wire with white stripe comes completely out of the connector. I tried to put it back together but every time I put the connector back into the ecm this particular wire keeps working its way back out. So I think it needs a new terminal on the end, it is very strange looking and doesn't appear to be female, which makes no sense-?-seeing as how the ecm has male ends. So it is like to male ends touching (ha ha) -- instead of -= if that makes sense to you. I am thinking junkyard but would love to know more about where to get a new one and figure out the right one.

You can use terminals from a donor harness.

Another option is to get a Metra radio harness adapter 70-1858 and use the terminals from it. Any local car audio installation shop will have these.

First picture on this page shows the retaining clip on pin. If you bend it out, then slide the end back in it will stay.

Awesome resources -as usual- you guys come through!

Upon further inspection it looks like at one time someone broke off a pin in this connector and that is why it looks like it has a male end in it.
