ERST throttle cable is held in place on the throttle by a metal clip on a ball at both ends same as a cosworth.

FRST has a slot for the cable to slide through and pin which is held in place with spring tension. Its similar to a push bike cable. At the pedal end its a rubber gromet and large ball to stop it pulling through the hole in the pedal.



In your case just use the correct cable.


For other setups that use a cosworth throttle body an Escort type cable must be used, although the pedal type does not matter as it can be modified.

Hope that helps.
