I have an L779 that I would like to add aux hydraulics to. It was an option its just mine doesn't have it. There is a plug on the main hydraulic control valve that is meant to be where you plumb into - I think the term is its a power beyond hookup? Anyhow it needs part 219609 that they don't make and nobody seems to sell for the fitting that the tube uses to hook into that spot.... I don't suppose anyone has a decent picture and possibly dimensions of one? I have a lathe and could possibly make my own.. I've found the actual aux valves used online but not this plug. Kind of killing me the tractor has the ability to run these directly but because of a missing fitting I'm going to have to go the universal route and plumb into the curl lines instead
