MF 1739E Electrical Question

[ellisco1]

Hi all,
I'm new here and I didn't find this when I searched so here it is.
Just bought a 1739E (haven't actually received it yet) I use and electric spray rig so I want to add a 12 volt switch leg on the rear so I can turn the sprayer on/off from the driver position. I notice that fuse 4 on the block is labeled "outlet". I didn't see any aux outlets on the tractor. Does anyone know what that circuit is for? To put another way, if anyone has purchased the service manual can you let me know if that circuit is up for grabs?

There is a connector that comes out of the wiring harness at the base of the ROPS on the left side. I think the tractor needs to be running in order for it to be active, I could not get it active the one time I checked it out while the tractor was parked in the shop. There is not a switch on it so I assume you will need to provide your own switch and connector with ground for your spray rig.
