I got a used 2011 Tacoma

Those are all relays.
I found this online:

Scroll to the bottom. They are labelled R1-R16

That thing on the window might be part of the aftermarket alarm, like Lojack or something like that. Probably has to do with a GPS tracker.

 

My question is why did you buy it with all those lingering questions?

And especially the key / fob. 2 working units should have been your request to close the deal

Along with removal of the alarm system

 

Welcome to TW...

 

I have no clue as to what that is on the window?!?

 

The piece on the window is the antenna to an alarm system. The button on there activate valet mode. The relay is the kill switch relay part of the alarm system.. my advice is to get a remote and code it to the truck. DEI is the company who make the alarm system… Viper and other name. You can follow the antenna and it will lead you to the module number then you can order the remote. Usually about $20 each

Also very easy to program the remote, using the valet button. GL
