The diagram on the motor seems clear. The left side is just an example of how it was wired, in this case, CW. (1 to 2) and (3 to 4), those two groups also get L1 and L2. For CCW (1 to 3) and (2 to 4) form two groups and each of the groups get a line input. So L1 to the (1 to 3) group and L2 to the (2 to 4) group. I believe the left part of the wiring diagram is just an example as to how it was wired from the factory.
What is not clear, at least to me, is the photo of the actual wires. Where are the wires coming from? Which are the motor wires and which are the line inputs? There appears to be large yellow, black, blue, and red wires. Are they from the BX conduit on the side? If so, why 4 wires for 120 volts? Was there some type of reversing switch at the other end of the BX conduit? Either way, I would just wire it according to the diagram and see which direction it will run. The worst that will happen is it will trip a breaker but if you wire it according to the diagram most likely it will run just fine.
It also appears to be a capacitor start motor since the one photo shows what looks like the case for the capacitor. However it could be a PSC motor but still nothing bad should happen when wired according to the diagram.
