I use a plug in arrangement to power my 16 gallon sprayer. The 1872 had a plug, but, it is gone now.
So I added one to the 2284. Boy I got lucky, there was an extra white wire hanging back there!! WOOT!
I connected this trailer plug to it.
The other end of that white wire was under the dash with another nice connector on it.
I added a switch, and a fuse.
The dandelions ain't got a chance!!
