The spring is contained within the lower of the two tubes that the pedal assembly slides on. The spring goes theough the bulkhead at the front and makes a 180 degree turn around a bushing/pulley behind the bulkhead and then comes aft between the two metal tubes where it attaches to the cable that goes to the black T handle. If memory serves correct, the cable goes through a hole in the release lever and is simply crimped with a small loop. The spring hooks on the loop. When the cable is pulled, the body of the crimp ferrule hits the lever and raises the pin. When the T handle is released, the spring pulls the cable forward through lever to remove any slack.
