On the bx23s I thought the port on the left was where you connect..
??
Step 3 in the video explains where everything goes.

You're completely removing a short "jumper"-style line from the Power Beyond port of the loader control valve that goes back to the tank port. Your new lines go from the Power Beyond port on the Loader valve to the 3rd function and then from the 3rd function back to the tank port.
Hold up, you have this confused. You're telling him the wrong ports.
The Summit site isn't working right now, so I don't know how they tell you to hook it up, but there's only 2 ways you can do it correctly.
You either hook it up before or after the loader valve. Neither of which involve the tank port.
First off, this isn't the loader valve, or any valve. It's just a block of metal that the hydraulic lines connect to.
Simplified basic hydraulics on the BX (trying to give a general idea, not an exhaustive explanation, for those that wish to critique).
On the BX hydraulic power flows pump - backhoe (if it's attached) - loader valve - 3 point hitch.
A hydraulic valve sends pressure to a hydraulic cylinder, allowing work to be done.
P is pressure being fed to a hydraulic valve.
Power beyond is an output from a hydraulic valve that allows hydraulic pressure to continue on so it can feed another valve further down the circuit.
T is used up pressure that is draining back to the tank to be re pressurized.
The
red arrow points to the power beyond from the backhoe if the backhoe is attached, or the pump output if there's no backhoe. Kubota calls this the P (pump) port in the manual. Land Pride calls it the power beyond in their installation instructions.
This port feeds hydraulic pressure to the loader valve (which is inside the front right fender directly under the loader controls) via a short hose (let's call it
hose A).
The
blue arrow points to the PB port. This is fed FROM the loader valve (from the loader valves power beyond port via hose, let's call this
hose B), and is effectively the loader valves power beyond. This is where pressure is fed TO the 3 point hitch.
The
yellow arrow is the T (tank) port. This is used up pressure from the loader valve. This isn't used in the 3rd installation.
You're going to hook up your 3RD function either before or after the loader valve.
If you're hooking up before the loader valve you're inserting the 3rd function between the backhoe and the loader valve (see
BOLD hydraulic diagram).
In this case you disconnect
hose A, hook the feed for the 3rd F to the port at the
red arrow, and hook the return to where
hose A connected to the loader valve. You have now inserted the 3rd F in between the backhoe and the loader valve.
You now have:
Pump - backhoe (BX23S) - 3rd F - loader valve - 3 point.
If you're hooking up after the loader valve you disconnect
hose B.
The feed for the 3rd F attaches to the loader valve where
hose B was connected, and the return for the 3rd F attaches to where
hose B connected to the hydraulic block. The 3rd F is now after the loader valve.
You now have:
Pump - backhoe(BX23S) - loader valve - 3rd F - 3 point.
Depending on the length of the hoses in your kit and what fittings you have/use you can either completely remove hose A or B, or you can simply disconnect one end and hook your kit hoses up to each of the open ports, paying attention to which connects to where.
For example the Land Pride instructions have you completely remove hose A, while WR Long has you disconnect hose B at the loader valve and connect there.
