Also, if I cut off battery negative end, is there any I will miss after it is restored? For example: if you take off the battery of an AUDI, the radio will be locked after the battery is put on again. A radio code will be needed to unlock the radio which could cost $120 if car is taken to a dealer.
Just want to make sure nothing will miss after battery is taken off.
You will be fine. I rarely unhook the battery anymore, I used to think the same that I could damage things, but if you aren't turning the lights on, hitting the brake pedal, etc you aren't applying voltage while you are working on the lights.
