long wires connect to the injectors on each end of the
fuel rail. The short wires connect to two inner injectors
(Figure 8).
8. Plug the FPS (fuel pressure sensor) connector into the
fuel pressure sensor under the fuel rail (Figure 9).
9. Connect the CAN cable from one rail to the other
(Figure 10).
