[QUOTE="Pheasant Surprise, post: 4355012, member: 1103"] Sorry I’m not up to speed with this thread at all. What is it your wanting - the connector and pin out for a 7-pin signal socket in the tractor? Your plug might not have all the pins populated only the ones it needs (conversely the tractor might not have all the sockets populated either). Pin Assignment 1. Radar - True Ground Speed signal (actual forward speed of the tractor). 130 pulses per metre driven (36.1 Hz/kmh) 2. Wheel Sensor - Theoretical Ground Speed signal (product of tractor drive wheel rotational speed and the rolling wheel circumference). 130 pulses per metre driven (36.1 Hz/kmh) 3. PTO signal - Rear PTO rotational speed. 6 pulses per PTO revolution (360 Hz/rpm) 4. Linkage In/Out signal - In-work /Out-of-Work (binary signal indicating three-point hitch is below/in-work or above/out-of-work and adjustable switching threshold). 12v/0v 5. Linkage Position signal - Position of the tractor three point linkage in the vertical plane between its lowest and highest points. 0 to 10V 6. +12V - positive power supply. +Ub 7. Earth - supply ground connection Pin numbering looking into the socket is anti-clockwise starting at pin 1 next to the keying tab, with 7 in the centre. On a plug it’s in reverse so numbering runs clockwise as you’re looking at the plug. Attached pic is numbering as looking at the socket. [/QUOTE]
