Forget what elect70 said its a auto not a manual. On the drivers side of the trans is the inhibtor switch will have a around 21mm nut and a couple of 10mm bolts holding it on. Take it off and there will be some srews holding it together open it up and clean up the inside and will be good to go the rev lights work off it.
