This one cable takes care of all 4 steps at once and skips 8 potential sources of bad contacts. Also there's no unneeded status LED which you'd have to remove otherwise as it would just drain extra juice for nothing.The phone doubles as a silent alarm/lo-jack so it's important in that context to keep the load to a minimum. easy to install and reliabe. the fuse is internal and self-resetting so it's actually better than a fuse holder.
