I am going to be installing 1) homelink mirror 2) an always on modded backup camera (needs to have switched 12V power & ground) and 3) would like to hardwire my radar detector. Is is possible to use the same light blue wire (switched 12V) and white with black stripe (ground) for all 3 items or will this overload, blow a fuse, not have enough power for all 3, etc?
