Hi,

To the best of my knowledge, this model year doesn't have one. The fuel pump driver is done by the VCM. I attached the wiring schematic below. Take a look through it and let me know if you see what you are looking for.

Take care,

Joe

See pics below. Note: I cut the schematic in half to make it readable. I did overlap the two so you can follow from one to the next.
