Installation method is described correctly, and where to get the cable and connector. Your problem is the loop of cable has to be the correct length. On my 49, I took my old rusty cable to Lowes, and made a cable loop right there in the store the exact size of the old one. Even got to use the special connecting clamp tool for free! Given no other option, I would take the seat bottom into Lowe's and use it as a pattern for correct cable length.
