Looked around here for some answers and couldn't find one, but if you disconnect the 3rd brake light will it throw a light on the dash? Only asking cause I'm switching spoilers and not gonna run the 3rd light.
I disconnected mine when I was installing my Mugen spoiler and it didn't set off any lights. Although a 3rd brake light isnt required, id suggest getting one if you don't want to be rear ended. The spoiler also didn't have a spot for the 3rd brake light, and where I'm at it is required, so I ended up taping it up to my back windshield and running the wire to my trunk. iJDMToy also sells these LED lights that replace the reflectors on the rear bumper, that can be easily wired as brake lights.
