There are others on this site who are more familiar with a 32 and will chime in with better information. But the intakes on 33 are considerably different than 1932, due in part to the the change from updraft to downdraft carburetion (though there was an update kit), the use of the Stromberg Model C automatic choke, and the vacuum power brake booster. On 33-34 there is a connection on the intake manifold via a flange and hardpipe that goes behind the engine to a junction at the rear on the driver's side. From there there is a takeoff for a hose to the power brakes, a small line for the Bijur chassis lubricator. If I recall correct and I'm going to take a look in the garage, the wipers are fed directly from the vacuum booster section of the fuel pump and the line runs up the left side A pillar.

The very small line with the loops on the manifold side of the engine is the feed to the oil pressure gauge.

PS - heading out to the garage to check on the wiper vacuum line.
