I actually started answering this last week but the site logged me out all of a sudden, sorry.
Anyway:
Essentially, on the Hot Rails you should have:
- A bare wire
- A green wire
- A red wire
- A white wire
- A black wire
Solder the red and white wires together and cover the joint with electrical tape.
Solder the bare wire to ground on the back of one of your pots or wherever else the nearest ground point is.
Solder the green wire to where the wire labelled "black" is connected on the diagram.
Solder the black wire to where the wire labelled "white" is connected on the diagram.
This should work.
