Extra 12v plug(s) on rear of 2009 John Deere 4520 ?

[shock]

I've received such great information here, I thought I'd press my luck....

I am trying to find an open/extra 12v plug on the rear of my JD 4520 CUT tractor so that I could power a 40 gallon Fimco sprayer.

Right now I have wires running from the battery that I plug into, and I'm trying to find an existing connection on the back to use.

On the right hand side, under the roll bar, I found a set of different wires. One says 'RF(indecipherable) ' and underneath that 'Forward (indecipherable)' on the tag, and has a loopback plug, plugged into it. I assume I don't want to use this for anything....

Next to that is an open plug. When testing with a multimeter, it gets power when I turn the Hazards/light switch all the way to the right-field position, I get power to the plug. I assume then that this plug is for the optional field lights? Can anyone confirm they had an open plug back there like that?

Any other options folks would recommend? I have open slots on the fender for toggle switches but assume I still need to find a power source.

Thanks in advance !

If that switch position works the way you want to run the sprayer, then you found what you are looking for.

I'm hoping ! Just don't know what the amps draw is from the sprayer vs optional lights and if I'll blow fuses or something. I'm not that good with electrical knowledge...

If you're not sure or don't want to use the wires back there, why not just make your battery wires permanent and install a switch and SAE connectors to the back of your tractor wherever you want it. That's how I've got one rigged up. I loop the wire around the ROP bar when not in use and when I need it, I just unloop it and connect to the pump. I mounted a switch on the ROPS too. It's a cheap solution.

Also, Fimco makes a wireless switch complete with sae connectors.
My wiring was easier, as I spray with a boom off the front end loader, so the battery is close by.

Previous lawn tractor with 2 gal sprayer I just put a plug to the rear tail light. When turning the lights on, the spray pump ran. Lawn tractor I have now has a cigarette lighter socket that is switched.
Don't think you will blow a fuse.
The Fimco wireless switch looks interesting ( $24 Amazon) but still need to get 12v power that is fused.

My spray boom is also on the front, but the pump is on a nurse tank that trails behind.

I just didn't want the extra wires hanging /running along the frame of the tractor

Got it. Then I'd just splice into the wires on the back and see what happens. Worst thing is that you blow a fuse. I doubt you'll have a problem, I think the wires on those Fimco wire kits are 18 or 22 gauge so it's not drawing a lot of current.

I have a 2006 4320 cab tractor. I had the cigarette lighter/ power outlet/ option ordered when I purchased the tractor. I don't smoke but I thought it maybe be a useful item later. It is on the left side of the tractor on the interior panel just beyond the hydrostatic range selector. I daisy chained from there to the outside rear of the tractor for my winch with remote control. The winch needed 12 volt. That's all I know.
