So, i got a little confused with the vac routing. Mainly because I was referencing this


I was confused because the write up said to connect the top of the BBV to the "tree" an the bottom should see atmosphere, but didn't mention anything about the SC bypass solenoid. Because of this I didn't know if i was suppose to run a line from the lower BBV nipple to the solenoid and have one of the nipples on the solenoid seeing atmosphere or if i should delete the solenoid and just have the bottom nipple on the BBV see atmosphere. After asking Snowth1ef I learned the the SC bypass solenoid should be deleted and that it is in fact the lower nipple on the BBV that must see atmosphere.

In order to possibly help others I modified the above diagram so that it showed the correct vac routing for a topswaped 3800
