If you have a premade cable, with a male connector on one end, and a female on the other, then you are supposed to cut it into two pieces (roughly in half, or whatever length you prefer), and then solder the appropriate half (female) to the tuner.

This was discussed here somewhere by Patrick et al, and a search may turn it up.

Perhaps Patrick could also add it to the tuner assembly manual, if not already there (?)

Cheers
