Positive Wires are usually red.
Red wire is Positive in a car battery. If they are not color coded, find which one is not connected to the chassis and this will be positive.
Both posts are gray, positive has a red wire running to it, and a plus sign next to it.
red
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
The black wire is the ground wire. The red wire is the positive wire. The green and yellow wires are the speaker wires. The white wire is the auxiliary wire.
I don't know about your car, but generally the darker wire is the ground, and the lighter one is the positive.
The positive speaker wire is a solid color, your negative wire should have a stripe on it.

The 1999 Subaru stereo wiring color codes are universal. The red wire is the positive wire. The black wire is the ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
Normally red or brown. The battery has a + stamped into it by the positive terminal. Follow the wires, on a modern car the positive will go to the alternator and starter. The negative wire (easier to follow) will go to the body/engine block
your an idiot. what color is the negative wire for everything. BLACK!!!AnswerI think it is the Red one. Red is the color code for the positive terminal (also for your battery tender). Black or green indicates the negative terminal..
