All cars with 4 speakers have 8 speaker wires (4 positive and 4 negative). The colors of the wires for these two cars are not the same. The only way to know which wire goes where is to get wire diagrams for both cars. Before cutting up your wire harness, check that the radio you're installing will bolt into your car and fit. Just swapping the mounting bracket may not work.
