The thin black line is going to the T splitter & the thin red line is not plugged in out of sight at bottom. U see the small green line. Red & green I believe are from trans & plug to middle & bottom right but wont stay running when I do. The biggest hose comes from brake booster & hasnt been moved nor has the one across from it & the same goes for the bottom right hose. Those 3 javent been touched. Js thanks

Yep, that is a large vacuum leak, if everything seems to work I would use a vacuum cap over the open port. Do you have any other lines that are not connected? Thanks for the image it helps.
