Vespa ET4 50cc 2004 Secondary Air System *Problem Solved *

[milly]

Well I got the scooter running but now need to connect the above up. I can see no info or pics anywhere all I have is the pipe blowing blowing hot air out of the right hand side and the sas unit sat in the topbox with two pipes leading off it.

Any info much appreciated.
