Whats up,
my 5th and 6th ports don't work on my 7. i found an awsome thread in the archive to fix the problem but when i was lookin in the engine bay i noticed somethings that i need help identifying. here's the pic:

whats the hose in red go to and connect to? and what is the ?sensor? in green for? and is it nessecary for the ports? cause they both seem like they are related to my problem? I am new the the fc. i mean i upgraded to a 2.5" exhaust without knowin about the auxilary ports.... Thanks

 

Red: Rubber hose that connects to the split air pipe. The split air pipe is also what supplies your aux ports w/ pressure. Get it back.

Green: ACV air dump. Put the rubber hose back on to quiet down air pump noise. Not related to aux ports.

 

when you say split air pipe. thats the pipe off the main cat to the that rubber hose. right? not to sound real newbie.....just want to make sure. cause i don't have that pipe anymore since the exhaust work. any suggestions?
Here's the link for the (i guess you cold call it a bypass value to get pressure to the aux ports) would this help eliminate the split air pipe? https://www.rx7club.com/showthread.p...light=air+pump
