You have to use switches because the Alpines want to see an "alteration" in current. If you just wire them straight, it will not work. Some indash screens only need to see ground on the brake wire. A simple toggle to ground will accomplish this. Alpine has two wires....yellow w/ blue and yellow w/ black. You can do one of two things. 1) Bypass with two switches. By doing this you wil be able to watch video and access features without having ebrake pulled. 2) Buy bypass adaptor. You can get them online, ebay and such. Pm me and I will tell you how to do the 2 switch wiring. You will only have to hit the switches once per start of the vehicle. Then you can toggle your "video" on and off if you are in a situation were you need the video not to be able to play.
