When removing existing power cord from old dishwasher, I "assumed" that it would have the 3 colors indicated. After pulling it out, I realized that there was a green wire & two grey wires with no discernible difference between them. Why would they do that? Now if I line up the cord based on facing the prongs, which one would be white & which black? for instance, left white, right black or visa versa?
Thanks…Steve
The green wire is the dishwasher's ground wire. You hook it up to the circuit's ground wire, which is the bare copper one.
I looked up the Honda EU2000i Owner's manual, and it appears these generators are only rated for 120 volt output.
I couldn't find much detail on the transfer switch you mentioned, but from what I could find it appears to be a 120/240V transfer switch.
If you were to connect the generator to the transfer switch, only half of the circuits would work, and you'd not be able to power any 240V loads. This is because the generator is designed to only supply 120 volts, whereas your home (and the transfer switch) work with a 120/240V system.
If you really want to proceed, which I wouldn't recommend. The adapter cord would have a standard 20 ampere three prong plug ("hot", "neutral" ground) on one end, and a four prong ("hot", "hot", "neutral", ground) plug on the other. The wiring would be as follows:
With this setup, only the circuits labeled "A" on the transfer switch will work (or maybe only "B" will work, depending on the internal wiring).
My recommendation; based on the fact that you seem to indicate that the power in your area is somewhat unreliable, is to purchase a larger 120/240V generator. This should plug directly into the transfer switch, and will power both legs (A and B), as well as supply 240 volt loads.

Use a multimeter set to test continuity or resistance. Touch one probe to a prong on the plug, and the other to one to the wires. If you get a reading, it means the prong you're touching is connected to the wire you're touching. Label the wires as you locate them.
NOTE: Do the testing with the cord not connected to anything.
Or go to the local hardware store, and pick up a new cord.
