Vacumn line diagrams

[apache 84]

Hi Guys, Has any member have a detailed diagram of the vacumn lines under the bonnet of a 1984 Corvette with crossfire injection,mainly at the back of engine.
I am just changing my dist again(3rd time)due to faulty new part.I have found a vacumn line that goes into large loom at the back of engine but I have no idea where it goes,withy out stripping alot of the car. It appears to need to be connected close to dist area and then disapears into loom heading to the right hand side of car,then loom disapears,not sure where.
All help will be gratefully received
Thank you

Sounds like your taking about the one that goes from the back of the throttle body, to the MAP sensor. Which is located on the firewall, to the left of the brake booster. h
