OK,.. sorry I'm so late with the pics. Yesterday we got a blizzard and several inches of snow while I was out. I was beat by the time I made it home.
Today I meant to take these pics 3 separate times, but forgot by the time I left the room. :-/
Yes, I think the cord you need is this:

I've always heard of it referred to as a "Single Lead" cord. It looks right.
I always like my machines to work as intended, especially the knee levers, because they're a part of the case, whether I convert them or not.
Therefore, for your viewing pleasure:
This is what the controller looks like at rest:

What it looks like when the knee lever is actuated:

And here's the bottom of the case:

The 2 screws you see closest to the top (where the knee lever hole is) hold the mechanism in place. The other three hold the controller. You do end up having to take all 5 out when you take the controller, if memory serves.
