In my owners manual it shows a 7 wire trailer plug, but my new to me TC45DA does not have one.

Is there a wire bundle on the tractor tha just needs to be connected to a 7 wire plug?

I would like to run my Herd spreader off of it.

What amperage is the auxiliary circuit/wire rated for?

Go to your local NH dealer or Messick's parts pages for your tractor and see if you can find a part number. Or talk to them on the phone.

Just looked at the wiring diagram for my tc 45d did not see any provisions for trailer wiring harness. If there was I doubt it would provide enough power for what u want to do. If it were me I would run my own dedicated circuit protected by a fuse directly from the battery. A 7 pin harness would have provisions for brakes , signals etc. all u don't need anyway.🍻

This is a common power supply connector in many tractors;

It is normally wire with one pin always hot, one pin switched power and one pin ground.

I think I figured out why my owners manual has it listed, it is the European version.
