Default J boot Vacuum connections 951

can anybody tell me what the 4th connection on the J boot is on the 951

the recirc valve

the AOS pipe

the vac pipe to the WGFV

and the 4th one, its pretty small, about 8mm and the hose 999 181 152 50 connects to it, but i cant seem to see where the other end goes

the reason for asking is, the J boot is going in the bin, ive got a silicon t piece 3" from the turbo to the air filter with a 25mm t off to the recirc/dump valve, i know i need to accommodate the AOS pipe back into the inlet pipe, the vac pipe to the WGFV is being re routed to the top chamber of the dual port wastegate (i think) but i dont know what the 4th line is and what to do with it

If you are using MBC and not CV for your wastegate you do not need the hose off the J Boot. The other small one runs to the Evap system near the test port.

If you're looking into the engine bay from the nose, it's to the right of the brake master cylinder iirc it connects to the fuel vapor diaphragm.

Gonna throw out the old J boot? If so, and if it's in usable condition, may I have it for the price of shipping? This for a project I have in mind.
