What does the B/R stand gor on the Vacume tree on the firewall.It's plugged up and I was wondering what it is I have 3 different Service Manuals and none of them say.????
What year is your car its plugged on....mass air. I'm sure its written on there for the baro on speed density. Map sensor for mass air..no vacuum for it.

Doesn't really matter what the tree says...vacuum lines can go anywhere...as long as what needs vacuum gets it. Your baps probably getting vac from the intake.
