Yes, the cables are pricey... But you will just keep buying them as long as it rigged incorrectly.
In addition to the cable, you are missing some other parts as well.
If you are interested, I have a complete black new style place diverter with cable, handle and everything you will need...
550 plus shipping
Or, if you want to spend let to get what you have working, I have those parts as well.
