The metal end of the outer goes in the plate with the hole in it, the little 'cylinder' of the inner goes behind a pair of the 'hooks' on the pedal mount as seen in that PDF. There are two positions that the inner can hook into.
Got my last cable from SpeedyCables, sent them my old one and this info:
"The length of the outer is 3320mm, which includes the engine end adjuster, which is 65mm in length. The inner is 3420mm, including the nipples; the engine end one is a brass barrel, fitted crossways, and there is a fixed stop 50mm from that. The other end has a small barrel nipple fitted lengthways, to fit in the slotted hole in the pedal."
They actually made the inner cable too short by about 20mm the first time but rectified the issue without a problem.
