Question on a gl1200 vacuum line.

imported post

Hey guys. i have a question thats been getting to me. I cant see to find in the manual.

I have a vacuum line running from my carbs to a black box aft of my tripple tree under the tank shelter and mounted to the frame. I think this is the CDI not sure though.

I have 1 line to that but before the black box the line is on a t splitter. The hose comming from that T is plugged. Does anyone know where that goes and what it affects.

Trying to get the pic from the manual but cant get it on adobe. Hope someone understands what I mean
