thats it. Not sure what the hose is for though. Just make sure its plugged into a siliniod (sp?) on the drivers side of the tranny. Floor it while your driving and you should feel it kick down a gear.

I think hose is some type of homemade adjustment. Doesn't the gas peddle rod strike it from the side.The hose would basically shim it up some to where the gas peddle doesn't have to travel quite so far???

Yes! Thanks for asking this question. I've been laboring under the assumption that the kickdown was wired to the stock carb that I swapped out some time ago. I need to reconnect my kickdown switch!
