[QUOTE="Big Red 88, post: 1359461, member: 18768"] should already have the vaccum line down there from the th350, th400's have an electronic kickdown (the one wire on the drivers side). but yes usually tap into the manifold for the vaccum modulator. if you want kickdown you'll have to get a kickdown switch from a truck that had a th400 stock, if i remember right they go on the gas pedal or underneath for that matter.
