I bought an Alpine DVD unit today. I hooked everything up and it works fine. MY only problem is you need to hook one wire up to the brake light, and another up to the e-brake light. To watch a dvd, you need to hit the brake, then put up the e-brake handle. The place I bought it from told me it can be bypassed by hooking up a switch. My only quesiton is how? Can I hook up both wires to a constant 12v source, then just switch the brake one on, then off, then turn the e-brake switch on? I'd like to be able to play dvd's while driving so passengers can watch it.
