2018 tailgate wiring

My 2018 came from the dealer with some loose tailgate wiring and I’m attempting to correcting it now. Where the backup camera wiring goes to the truck is a plastic snap fitting. I tried installing it several ways but it still won’t snap into place. How is it supposed to go? Been screwing with this for an hour and I can’t get it into place. Thanks

 

You’ll need a new grommet it looks like.

if you buy the tailgate lock from Toyota that should have been stock it also comes with a new grommet.

two for one, but expensive.

or, someone on here that has their old grommet can send it to you. I do t have mine anymore, otherwise I’d offer it.

 

thanks! I managed to reinstall it. Then I started looking at videos of thieves stealing tailgates so I addressed that issue also.
