New Holland Workmaster 120 (decoration?), Massey Ferguson 135 (does all the hay work)
I have a sprayer I would like to connect to my WM120. Unfortunately, the pinout I was given is not working for me. I ended up blowing a fuse (and hopefully not also the relay) tinkering around with stuff (bad multimeter connection, fixed) but now that things are connected correctly on the meter and a new fuse is in I am not getting voltage on what the diagram below says are the correct pins (ground/white, +12V/black). Wondering if there's a different pinout for the New Holland tractors than what is shown. All I need is +12V to my sprayer pump, and I had wanted to use the 7-pin connector to supply that so that I can avoid running wires to the battery, etc. I prefer short, sweet cable runs.

Any idea if the NH pinout is different than shown? I do not have a diagram in my owner's manual and am not sure the below is trustworthy. Not a fan of blowing fuses. Thanks for any helpful replies.

Do not use a vehicle diagram. You want agriculture. Here is a link.

Thank you very much. I'll go out and have a look at this later today and see if it helps. Looks like either pin 7 or 4 would be appropriate.

I don't know why New Holland couldn't include a pinout picture in the manual... Giving pin numbers with no picture is pretty useless. <haha>

Nobody does unless you get the tech manual then there’s a better chance you’ll have a diagram however I gave a NH and there is no diagram for what wire goes on the flasher button. Was a guessing game. Never did get it correct but it works. Calling NH yielded same results as what was in tech manual

Solved the problem. Thank you! Not sure but it seems the polarity is reversed (multitester showing a negative voltage with black wire on the ground pin (top pin) and red wire on the center pin. The bottom pin (#4 in the diagram at the link above) seems to be not connected.
