I'm working on restoration of a 1962 M151 and I wondered if anyone out there
knows the proper routing for the air lines on the pneumatic wiper motors. I
figured out by trial and error that the vacuum line off the vacuum pump goes
to inlet on the motor closest to the windshield. They will work with just
this one hooked up, but they are a little sluggish.

The outlet on the wiper motor closest to the driver seems to want a positive
pressure feed (at least I can feel suction when the motor is running) The
manual isn't much help, just shows photos showing two separate lines coming
up out from under the dash to T's. From the T's they split to the two wiper
motors, same inlets.

Anyone know where the positive pressure line is supposed to end up?
