Always nice to hear alternate ways to do hydraulics.
On my MF, the hydraulics were plumbed from the pump to the FEL valve, and then to the 3ph via power beyond on the FEL valve. I interrupted between the FEL valve and 3PH for the backhoe pressure line, and I return the BH right to the tank instead of running it through the 3PH. This keeps me from accidentally using the 3PH with the BH on, since I don't have to completely remove the 3pt arms to mount the BH. If I do need to raise the arms slightly, I simply plug the BH return into the other side connector, which feeds the 3ph, but I don't leave it there.
As for TnT, I had planned to use two diverters off the FEL valve, and have both engaged at the same time via a toggle switch. This way the FEL valve would either control the FEL, or the TnT. I figured the movement of the FEL joystick was more "intuitive" to tilt forward/back, or left/right than having two remote levers that both move forward/backward...
Having an actual remote valve is another option though.
If you have BH plumbing, you already know where to get the pressure feed for the remote valves. If your BH connects to the same two fittings that you must then connect when you remove the BH, then it's returning through the 3ph, and you can interrupt either of those hoses to run the aux hydraulics, and they'll work with the BH connected, or not. If your BH dumps straight to tank like mine, where one of the BH hoses plugs into a fitting on the tractor that is not otherwise used, then you need to interrupt the pressure line before the backhoe to have the remotes work with or without the BH. (This is the line from the tractor that you unplug from a fitting on the tractor and plug into the backhoe...)
Good luck!!
