do i need to unplug the battery for these mods?
In college I had to do a "how to" project for a paper, so I did it on removing a battery and found myself listening to the engine and road noise after taking pics for the project. Mine locked. I took it to the dealership and got lucky a friend unlocked the radio for free, and made it so it would not lock again.
You picked a good mod to start with, good luck, and happy future mods.
