I have just bought a new Holland 650 from my mate - he usually does all my baling but I think he wants me to do the small bits myself now! - anyway, my question is can the electrical connection for the control box and the duckbill motor thingy be connected via the three pin connector in the cab? My mate runs his other balers, both NH, directly from the battery and says this is the way it should be done as stated in the manual.
