vacuum - Toyota Corolla, 1.6 L, 1989

Today I decided to put a vacuum to turn on the differential, but I had to sweat a little, since the book did not have a diagram on how to connect it, and the former owner took off the hoses and worked somewhere from memory, as I saw from a friend, well, there’s nothing like connected) The problem with electro bugs is one of them it was broken off and had to be done, but it was small in size, so I had to drill a hole and insert a pre-cut iron tube there. voposchem, then the system there is not complicated there is a vacuum from which the hose departs to the coupling in the distributor and 3 hoses depart from the coupling that go to 4 electo valve that's the whole system.
