ok, last night i installed my cp-e system. i used the scotchlocks and i'm not 100% trusting of them, so i want to verify that they are all functioning. since my car is still in storage and i'm driving around a 1993 grand am for the winter, anything will fel fast. i've read to take voltages and blah blah blah, screw that. i bought that part the put it back to stock instetad of the box (basically it puts the mafci wires back together). so i'm going to test it by driving with my box on and then with it off. my question was: do i have to unhook the battery to install that little part? it seems like i should because i'm dealing with wiring...but i wanted your opinions.
