if you got a KE70, you don't need to change the cable technically (ive found there are 2 types of throttle cable brackets on rwd manifolds, both will affect the fit of the cable so only buy it if you need to). KE70 works, AE71/adm 86 doesn't (and most people just get a ke70).
Wire with engine in the car and loom on the engine and plugged up.
