Call L & D Ag Service and ask for Ted. They can make up the wiring harness you need or supply a generic Raven and sell you any parts you need. The hydraulic flow control valves as I recall are around $300 so it may be better just to scrap the one you have and use a new Raven valve that will sure work with your controller. L & D is where I get all my Raven stuff. Good people to work with.
