Throttle Body Elect Connector Problem

In removing the TB to clean it, I followed instructions and rotated the elect connector counter-clockwise and removed it fairly easily. I didn't think any locking tabs, etc. broke.

I can see the spiral ramps molded into the plastic connector, and one might think it's supposed to rotate back together opposite to how it came apart.

There are two white arrows on the connector and one arrow on the TB. I saw how the arrows lined up before taking apart...

Trying to reinstall it, I have the pins lined up but it's impossible to rotate to lock it in or even to just push it in firmly until something locks. It appears to engage fully, I think, but won't lock into place. Two arrows are lined up when the connector appears seated, but no rotation and no snapping together.

The plug would vibrate and fall out unless it can be locked in.

Did I break some plastic lock pin when I disconnected it?

The book gives no detail and I've searched here.
I need someone with hands-on experience.

OK, Ok now

I looked at it again and found the rotating locking collar was sticking due to dust/sand particles or plastic slag from the casting process... I rotated back and forth to get it to move freely.

Now it's together as it should be.

Only took 45 minutes
