I have done two ways , on the e12 based 6 seris the 1st years that came motronic had a different pedal setup with a cable that comes into the car , if you can find all the pieces that way works best
the other way is like what you mentioned , I think I used an e26 cable ( its been 15 ish years and memory is fuzy ) I drilled a hole on the bell crank dealio on the bottom of the block inserted a gromet there and the canle fit right in
