Getting ready to install a WR Long 3rd function kit on a Powerstar 75. The hydraulic portion of it is simple enough. The electrical instructions are not as detailed. I plan to use the existing buttons on the joystick to work the 3rd function, so i purchased the WR Long kit type for that plan. I hear the relay firing when the button is pressed on the joystick but I am unsure where the other end of the connection is for hooking up the WR Long wires. If any one has any wiring diagrams or past experience installing this type kit on said tractor. Thanks
