'Terminal blocks' usually refer to the kind of arrangement where you push the (bared) ends of the wires into the holes and there is a screw arrangement to clamp them in position. Personally, I would use thin screened two core cable for this. I use Evolution XPC 301 cable for this sort of thing (and for MIDI), but I don't know if or where you would get it in the US. Maybe one of your compatriots can suggest something suitable?

If I'm right about the terminal blocks you won't need any sort of termination at that end other than the wires themselves.
For the other end I would expect that 3 pole 0.1" Molex KK female housings and crimp terminations would be needed.
You can assemble these by hand using needle nosed pliers, though it's a bit fiddly. Maybe you could find someone to make them up for you. I rather doubt that you could source what you need ready made, but good luck!
