Throttle cable broken

Yes. Don't attempt to feed the new cable all the way to the engine.

There is a flex conduit between the tunnel and the engine. Pull the flex off the tunnel exit. Feed cable to this point, then push cable into the flex.

You may have to reach up over the tranny to get the top end of the flex into the opening in the engine "breast plate".

Another method is to feed a "pull wire" down the flex conduit from the engine and then attach the cable to it underneath.

Thanks a lot Jim, the cable is now installed.
