There are no tricks ...
Remove carpets, pedal board, center console (if installed), center tunnel inspection plate and driver's seat
Pop connector at pedal loose and remove ball connector and nut.
Disconnect cable from throttle body in engine compartment and push it down thru the engine tin.
Crawl under car and pull the sheath loose from the firewall and pull cable out of tube.
push new one back thru and secure metal end on stub in firewall. You can push the sheathing back up through the engine tin.
Back in the car, fish the throttle cable end out of the center tunnel. Using a mirror, make sure it is not wrapped around the clutch cable. Put the lock nut on threaded end, screw the ball connector on and snap it on the bell crank.
Reassemble remainder of interior.
Go to engine compartment, secure sheathing to mount, pull cable and secure with barrrel connector to throttle body.
