ooooooh i hear ya ( lively ) it was that the seller didnt know either..he just bought the dragster for the motor.he didnt care how all the buttons worked..just that it had a 632 he wanted..or to sale the motor and then sale the dragster roller..and the old owner is unavailable.sooooo i have to figure it all out..some times its easyer to ask,so it can lead me in the right direction..because man is it a pain in the asss to get under that dash in this thing...and yep its for my son..just got back from Memphis buying a motor for it..
