Hi all, I just got a 2013 ES 300h ! Avg 37.1 mpg !! I am so happy I sold my gs350.. I am installing hid fog lights and am having problems with them both firing up. These are the plug and plays. So I am planning on using a relay harness but need a 12 v power supply. Since the battery is in the trunk, I found a terminal in the engine compartment fuse box, and was wondering if anyone knew what it is used for and if it is ok to tap 12v to power the fogs from here? I have attached a picture and circled the lead. Thanks in advance...
