dono if this question belogns here, but where dose the thick vaccume line from the brake booster go to?. I was swapping out the s240 and I came by this vaccume line that attaches to the brake booster, and goes across ontop of the firewall and then goes south of the firewall. Dose this belong to the intake mani?

 

yes, it runs to the intake manifold, if it is not hooked up not only will you have trouble keeping it running but wont stop worth crap either.
