mine is bolted onto the front bulkhead, measure it up so that when it is flat the hole in the top of the pedal that the cable goes through is just at the top of the bulkhead just before the step down (looking at the bulk head you will know what I mean, drill a hole in the bulk head and run teh cable through it. (I used a mountain bike brake cable adjuster like you get on the handle bar end) this allowes the cable outer to stay in place and teh cable inner to run freely.
