A new handle on the joystick with a water proof momentary switch on it.

All the ports on a subplate are capable of about 5000 psi.
You can insert the 3ed function valve anywhere after the FEL valve, but before the 3pt valve.
The 3ed function T port can go to tank if that is your only valve or last valve in the hyd circuit.
Any action you do with the 3ed function, will be reflected in the FEL valve relief.
You can also insert a relief valve anywhere in the hyd circuit for protection of a cyl or motor, etc..
I'm with the OP. For the money, I would just buy the OEM kit. The integration is PERFECT and hard lines are employed along the loader. For the same money as an aftermarket setup I just don't see any reason to go with the aftermarket setup.
That being said...one of these days I'm going to do my own from Surplus Center for ~1/2 price.

I'd very interested to know where you're finding all of the parts diagrams for this. I'm trying to figure out exactly how to do the same thing on my B3200 ( add a true third function, instead of just a diverter) - and as part of the investigation I'd like to see how it's done on the L4240
Where does the PB go on your tractor "normally"? On mine it would go either to the backhoe - or directly to the 3pt.
From your description it sounds like the solenoid valve might have been installed in the line that normally goes to the 3pt - so now when you want to use the 3rd function you're "diverting" the fluid that would be going there - to the 3rd function instead.
If so- it sounds like you've the same type of setup on your tractor I was thinking of installing on mine - if possible would you be able to get any info off of the valve that solenoid valve you're talking about?

To clarify....
"The 3ed function T port can go to tank if that is your only valve or last valve in the hyd circuit."
In my build the 3rd function would be before the three point connection.
So the "T" port from the third function sub plate would feed the three point valve???
Power beyond to the three point valve?
Thanks again for all of your patience answered everyone's questions. It's greatly appreciated!!!
Kubota Factory 3rd function
I have a kubota 3rd function valve & connections on my M5140. The dealer installed it on the bare used tractor at the same time he installed the kubota Loader (LA1153) on it. I am installing a grapple next week and I want to plumb it so when I push the kubota loader control Joystick TOP Button it will open the grapple lids and the LOWER Button would close the grapple lids. Does anyone know if there is a standard or uniform way they install the system so the coupling mounted on the loader frame bulkhead are mounted the same on all installations? Example the top coupling in my case it is the Male coupling (see picture I have included) would be the pressurized line when I press the Top Button. I know if I just install the the hoses and couplings to my grapple I have a 50% chance of being right. I am just trying not have to reinstall my couplings and get hyd fluid all over the place. Or can I just reverse a electrical plug at the Joystick area?
I guess what I am trying to ask is here a standard or uniform way the Kubota Factory 3rd Function Install is installed? Thanks in advance
