Throttle cable safety clip - Where does it go???

My throttle cable came with this tiny strip of metal that I'm told is a safety clip. Where does this install? I'm sure somewhere by the pedal?

Thanks,

Steve

Is the throttle cable the kind where it's square plastic going through the firewall?

If it is it goes behind/through one of the plastic tabs on the inside of the firewall to lock it from pulling back out through the hole.

Thanks Sputnik!
