I wired mine to the acc terminal on the ignition switch with an 10 amp inline fuse. I only use it to charge the phone.

You need the following connector which was made for this type hook up (threaded screw). It just pushes on and will not fall off. It is insulated and is the eaisest connector I have ever used.
It is AIRTEX Part # 1P1063
You can get it from O'Reilly Auto Parts
