Schematic or installation pic is not included. Just guess which wire goes where. Don't bother calling Porter Cable's tech support. They don't answer.When the wiring is correct, watch the pressure closely. The one i installed today ran until I noticed the pressure was almost at 200 psi. This is rated at 135 psi!!I shut the system down. I called Porter Cable's tech support line. After 20 minutes of waiting, I didn't wait anymore. I'll return this one and hope it is not resold to some other unlucky person.
