Ok, I know this question is stupid, but I want to make sure that I do the right thing.. Let's say I am trying to install a relay. The relay have two wires that connect to the car battery's positive side and negative side.
1, Should I connect the positive wire to positive first or negative wire to negative first??
2, Does it matter if I connect either wire first???
3, Let's say that I have to disconnect the battery from my car. Should I remove the negative wire first or positive wire first???
4, Which wire is ground wire?? positive or negative??
Please help!! thanks
