CCV help 323i only has one port off air distribution rail...

I am in the middle of replacing my ccv valve.



I have taken everything apart but ALL the diy pictures i can Find show two hoses running to the air distribution rail. One hose in the front and one close to the cabi.



I only have one connection the the air rail... In the front. i ordered car specific off of autohausaz but it listed the system that looks like all the pics do. one different from my vehicle...



I have 1999 323i ... Any thoughts?
