It's really easy to install the switches, but it's just really ghetto.. With the TR-7 it's on all the time.. It's still recommended to get a switch to disable the TR-7 in case you ever need to prove you can't watch video while your vehicle is in motion.. Hide the switch under your dash and when it's activated, it's back to 'Video has been disabled for your safety'..
rocky, they are about 20 bucks on ebay, it's a little module, 5 wire hookup - power, ground, remote, ebrake, footbrake, + 2 other wires that don't get used. the box itself is about 1.5"x2"x1".
I just bought a little switch from DLC that I'm going to hide away somewhere, or maybe I will put it by my cig lighter. I don't want it to be in the way though, cuz itll prob never get used
