anyone got a vacuum diagram for a 67 cougar? i'm trying to find out why these blasted doors wont open for the headlights... theres one hose thats disconnected up by the firewall that has no visible place it can plug in, but it plugs into the distribution block. and one actuator opens the door when i apply vacuum to the lower side, bot does nothing at the top side, the other door will close if i apply vacuum to the top side, but does nothing if applied to the lower
