Connect the black to negative and red to positive.
Use an ohmmeter to determine which of the white wires is connected to the chassis. (One lead on a non-painted nor rusty part of the frame and the other on the wires.) The one with near zero ohms should be connected to the negative terminal and the other to the positive.
