The two hoses are for the power steering.
Tells the power steering your speed so it can adjust.
If you dont have power steering, take a 6" vacuum
line and plug one end on one fitting and the other
end on the other fitting. Acts as a plug.
Check the top of the speedo housing and see if it is
broken off. There should be a keeper slot in the top
of the connector , a keeper spring retains the speedometer
cable in that slot.
Lots of times they are broken (at the slot) on swap motors.
I just had to replace one.
