Can I use an add-a-fuse to the fuse block to power the V1 or should i tap into an existing wire? Can someone tell me what is the best/easiest way to do this, and if possible show pics?

Also, How can i program the doors to lock when I start to drive? Does the dealer have to program, or can i do this myself? Thanks and sorry for the newbie questions, but I dont want to mess anything up!
