Ok I have two quick questions to ask for my,
1990 fox with the stock 5.0

1: On the driverside of the firewall there is a black vacume connecter. It has a B.B., S, A/C, B/R and a S/C imprinted above the vacume lines that go into it. I already have the B/R and A/C pluged off. My question is what is the B/R and can I plug it off?

2: Does the MAP senson on the 1990 5.0's have a vacume line going to them?

Thank you for your help.

1990 has a BAP sensor= no vacuum line.

not sure what B/R is but you shouldn't need it. The vacuum tree just takes vacuum from the intake and distrubets it. I got rid of mine and ran all direct to my gt-40 intake

Your B/R should already have been plugged, i believe.
