Need some tech advice rather quickly. Work in a body shop and we have a '30 Model A that we're working on. Need info on routing of vacuum windshield wiper motor line. Have line from manifold to firewall and inside firewall. How is it routed from there up to the motor? Model A is a closed cab pickup, original. TIA for any assistance.

As the Moderator, I would like to WELCOME YOU here....

I have never owned a Model A ......but on a 1932 Ford roadster.......the hose goes up on the windshield.



If you look closely........in the upper left hand side......of the windshield..you can see the metal line (chromed) .....going to the windshield wiper.

DEUCE....

Don't know if this is any help . On my coupe I mounted a electric one in the original spot had to do alittle modifying, then under dash wired in a terminal strip took piece of wire with switch mounted in it, if I need the wiper just connect my leads from strip to wiper it hangs in the way , but if if you don't use it that often, take the wire off put it in trunk till needed.
