Automatic Lights
 

Is there anyway to set this up in a 2013 FRS

As in headlights? Yes but you need to get an oem module from a tc I think... It's involved.

Yes is there a diy or is it really involved

I am not sure.. The ecu supports the functionality. You need the sensor and control unit I know for sure. I cannot recall a diy but that doesn't mean it doesn't exist. I did not Google for it. You can try ;-)

Edit : I say that it will be involved bc you will surely need a new lights stalk which involves removing the steering wheel. That is if you want it to be like oem

This is a writeup that Moto Miwa on Club4AG wrote up a while ago. It's not OEM function, it utilizes an aftermarket automatic headlight circuit (DEI 545T) but it works fine for me. I've been using a similar setup for over a year now.
