PLEASE HELP !

I have just received a second hand HKS SQV BOV for my 93 FD3s, but there was no installation instructions going with it and I am no expert so if anyone could help me og give me a link to where a can download a installation instruction to print I would be very very happy ! allso, according to the guy in Japan from whom I bought the BOV it should be complete and just ready for bolt on, but I am not sure if something (maybe just a little) is missing ! I have taken a picture of the BOV as it came, if you can see something is missing to complete the installation or if it is just ready for bolt on please let me know. Thank you very much. ;)
