I didn't need to unhook the battery to reset the computer did I? It was easy except the new wire was twice as long.

 

You shouldn't have to reset anything unless you were getting a cel for the O2.

 

i would take the negative terminal off anyways.....just in case... if you got a new O2... you might wanan reset ... it may not be manditory, but just in case so itll reset it.... of course itll reset your presets on your radio and reset your clock and equilizer on your radio.. but that rakes a minute to fix again
