1984 308 QV Fuel Injection system routing

Hi! This is my first post and I would like to congratulate all the members who maintain this amazing forum!

I feel a little embarrassed to ask this but anyway.. here it goes:

I'm working on a 1984 308 QV, there were several disassembled parts and was a real pita to make the engine start but in the end I made it (kind of). There's 2 ports on the fuel distributor/k-jetronic system, one is for the auxiliary air valve AAV, what about the other port?

I have searched everywhere, diagrams and photos. All systems seems to have only one port, the one for the AAV.

Could someone be so kind to help me with a diagram or a photo showing the 2 ports/hoses?
