[Closed] another parameter wiring problem

So I’m having trouble getting some parameters moved from one object to another. I figure the best way to do it is with a script that picks out the following:

for each position controller:
grab the expression
the control it is wired to

then place that information onto the target obj.

i can create position controllers, and i can do the wiring, but i can’t find out how to get the expression, or the control it is wired to. is there a way to do that?
