Which hose connects to which side of it's stick?

How do I know which hose connects to which side of the excavator's/backhoe's stick? The hose connectors in this video look the same. The reason I'm asking this is because I compare this to a diamond blade on a cut-off saw spinning in the wrong direction. Diamond blades have a special arrow engraved on them to tell the saw operator which direction the saw blade needs to be spinning. Otherwise, the diamonds in the blade will not be exposed to the material it's cutting and very poor cutting will result. So if I connect the wrong hose to the wrong side, the hammer's/hoe pack's motor will get messed up.

While I'm on this topic of hoses. Why do some excavator attachments have more than 1 pair of hoses? Such as those 360 degree demolition shears/processors that have up to 6 hoses? It's similar to how Diesel 10 has 4-6 hoses for his claw. What do those other hoses do besides pressure/return? And why do some hammers have what looks like a third hose running towards them? Not all hammers have a third hose.

Since it is an 8700C, it should have a 4 way valve .
Overpressure protection
Overflow protection
Reverse flow protection
Motor shutdown freewheel

Staring at the nipples in front of you, the nonexistent LH is supply (38-43gpm @ 2300psi) and the nonexistent RH is return to cooler/ tank.
Since someone removed the $800 valve, the furthest from the carrier (the bottom of the motor) is the supply.

Maybe I didn't explain this thoroughly enough. Let's take for example this Kent breaker. The right side hose is designed to connect to the right side of the excavator's/backhoe's stick while the left side hose is designed to connect to the left side of the excavator's/backhoe's stick. So if I connect the left side hose on the breaker to the right side of the excavator's/backhoe's stick and vice versa for the other hose, then the attachment's motor's going to get all messed up. That's what I mean when I say "if I connect the wrong hose to the wrong side, then the attachment's motor is going to get all messed up or the attachment cylinder circuit is going to be reversed (left is right and vice versa)". This same thing applies to hoe packs and 360 degree rotating attachments (shears, processors, clamshell buckets, etc.).

So how do I know which hose connects to which side of the excavator's/backhoe's stick? This is why I compared this to a diamond blade on a hand-held cut-off saw spinning in the wrong direction of the arrow engraved on it's blade. And yes, looking at that Allied Hoe Pack in the video I provided, the hose connectors on that loader connected to the hoe pack look the same.

And let's take for example this Stanley hoe pack. The left side port connects the hose to the left side of the backhoe's stick and the right side port connects the hose to the right side of the backhoe's stick. But with this Genpac hoe pack, now I can't tell which hose connects to which side of the backhoe's/excavator's stick as the hose ports are sitting vertically on top of each other instead of side by side.

Ok, I just found this. See how on this NPK breaker, the right hose is hooked to the left side and vice versa for the other hose? And I certainly don't operate a skid steer loader. See how the ports are sitting on top of each other on this Deere track skid steer loader? Now, I can't tell which hose connects to which side if the hose ports on the attachment are sitting horizontally and on this skid steer, the hose connectors are sitting vertically.

A hydraulic hammer won't run when oil is reversed, so, connect it one way and see. Reverse if necessary.
If someone hadn't removed the valve on that 8700C, and you connect backwards, it simply wouldn't run.

Ahh ok, because remember that Stanley HS-6000 I've shown above? It's hose ports are sitting side by side. So that tells me "right hose connects to right side, left hose goes to left side of the excavator/backhoe's stick." But on this Deere skid steer, the ports are sitting on top of each other. So if I were running a skid steer loader and the hose connectors were sitting on top of each other, then I would be stumped on the connection sequence. But for that Genpac GE-970 also shown above, it would be easy as the ports are sitting the same way as the ports shown on the skid steer.

I don't think that's quite right. I have several hydraulic attachments. The ports/hoses on the attachments don't always match that of the carrier machine, regardless of whether the ports are side-by-side, or above and below. As a general rule (and I think someone already stated this above) the carrier hoses are thus:
The left side line is usually pressure, and the right side is usually return. I have a relatively new Allied 8700 and the right side hose goes to the line on the left side of the stick, and the left side hose goes to the line on the right side of the stick (the hoses are crossed) when mounted to my '20 CAT 305.5. On my 5,500# Toku breaker the hoses are matching right to right, and left to left. I could give more examples but you really need to consult the manual or the MFR to determine which line is pressure and which is return.
