Throttle linkage to cable
 

Ok I picked up a Lokar throttle cable and I have NO IDEA how I am suppose to do this conversion. How do I hook the cable up to the pedal? There has to be some sort of bracket that i need to get inside the firewall to hold the outside part of the cable otherwise the whole cable would just move if I would move the pedal. Or does the cable just like bolt on right to the firewall somehow? I have looked everywhere and cant find anything on this. Ive seen plenty of cables in place of linkage but cant find anything....
