Which wire goes where on a playfield 2N5879

Hold the transistor with its face to the left, legs to the right and the long part of the case upward. The far leg is the base: it takes the white/red/red wire from the driver board and the pull-up resistor. The near leg is the emitter and goes to the coil lug without the diode band. The metal case is the collector and takes the green ground.
