'81 turbo. had a barn rat eat the vacuum lines under the hood.(amongst other things. if anyone ever tells you they only eat the insulation, that's BS.) copper in the rat turds is indicative of metal ingestion. got the wiring pretty well sorted. but the three vacuum lines across the rocker, and what and where they hook up is mystifying me. any help much appreciated. as i understand it, the '81 is unique in this aspect; as to components and routing of the speed control and which vacuum line goes to the interior vacuum motors. thanx in advance.
