hello, its been a long time since i posted, i had to creat a new account because i forgot my user name. i have an 03 mdx and there is a relay sized box on my firewall that i can't figure out if its missing a vacuum hose or not. does anybody have this too or can tell me if its ok or not.
thanks

 

There is no vaccum line that goes to this box. For some reason I believe this is a filter box for a fresh air vent, but what system I cant remember although! Rest assured although that there is no line that is disconnected.
