Underseat storage issue, what is this?

So I was cutting out the back to fit my underseat storage and found this. It wasn’t on my ‘16. Any clue what this is for?

 

It is related to the remote lock/unlock but I'm not sure its for the FOB or the remote connect services. Either way don't damage it .

 

It’s not damaged but seeing if I can move it. Humm

 

I would leave it alone. I have the same storage and it doesn't interfere with the installation.

 

From ESP's site - https://www.esptruck.com/product-page/toyota-crewmax-rear-under-seat-storage-unit-1:

Compartment measures 4" deep Fits ALL 2014-2021 Crewmax For 2020-21 with Smart Key, care must be taken when cutting out foam in center compartment due to wiring harness under foam.

 

I just spoke to the guy at ESP, and it is the sensor for the wireless key and unlocking the doors. The new box he said is shallower to fit over this piece.

 

Yes. It states this on their site. I must have the upgraded storage as I've had no issues with the storage laying flat.

 

So we got it up, which was a complete bitch cause we couldnt see exactly what we were dealing with. We then tunneled out the back side and tucked it under there out of the way. Fit the storage unit in and tested all the keyless stuff. Everything is fine now.

 

Looks good.

 

Which brand of rear floor mat are you using on the truck?
Thanks

 

Husky X-Act

 

Nicely done, that looks awesome.

 

Just curious but do you have to take that box out to clean or empty your floor mats every time they need to be cleaned

 

I have the longbox setup and no, I can tuck the husky liner up under the lip.

 

Looks good
