Pneumatic signal. Added pictures — Toyota Hilux Surf, 3.0 liter, 1994
Bought on the occasion pneumosignal. Compressor, 2 pipes, hoses. The seller assured that it was a very good production in Italy. Packed in plastic and it was not possible to see in more detail in the store. The first test took place at a friend's shop. Since it was not possible to connect everything to the electrics, and none of the pipes was blown through the "mouth", a pump was taken from the ball. Having connected to one of the pipes, a test "zilch" was made, after which the hearing in one of my ears temporarily deteriorated. Satisfied with the sound quality, he left the pump alone and began to study the design. Everything is not done very well, according to the pipes, it’s a waste, somehow they are easy to understand and in general it is clear from the quality that the naked china is not of the best quality (if you had the opportunity to look in the store, you wouldn’t buy it). My fears were confirmed over the weekend when I started to put a pneumatic signal.
With difficulty I found a place for installation, installed everything, extended the wiring to the Akum (where I still had to find out where to get the control signal), put the relay there and started testing. With 2 pipes connected, there is no sound, or rather it is loud, but it looks like a signaling signal. interrupted, the compressor is clearly not enough. We connect one all buzzing. The wiring that I installed quickly began to burn and overheat (0.75 in non-burning insulation). At first, I sinned on the wiring, but after replacing the wires with power ones in 4 squares (like), the state of affairs with the sound did not change at all. But yesterday I found where you can connect the control wire, it turned out to be very close to the Akum. I think I need to roll up tomorrow to quarrel with the seller.
In the future, it is planned to connect the compressor through a reduction gear to the tubes of the bridge breathers, in order to blow in 0.1-0.15 atmospheres if necessary.
And here are the promised pictures
The kit itself. Relay for as much as 40A
Planned installation location
Love the engine compartment with the V6- as a table you can place all the necessary tools
This is how it happened. still with the old wires. Wiring not installed.
Old wiring next to the new thicker one. Unfortunately the replacement didn't solve the problem.

On the previous car was everything was buzzing. And a couple of times I ate water and there was nothing to gurgle and buzz. I put these in the far corner, so that less dirt gets in. I'll post pics and you'll see.
dudki vesch cool! Their current, as I understand it, still needs to be serviced! I installed it with one pipe, after a couple of months it started blowing like a dull thing. I disassembled the pipe itself, cleaned it (dirty condensate gathered) and installed everything in its place! blowing, her mother, blowing as before!
Well, for what the breathers are displayed in the engine compartment, I think it’s understandable. So, if the water obstacle is not large and it can be flown over on the move, then even regular breathers help, if it is a wide stream or a large spill on the field, then simply bringing the breathers into the engine compartment is enough. Well, if we say sit down in a stream where water constantly flows, then seals that work well in one direction (hold oil) push through and water enters the bridge. It’s not a big problem, it seems, you don’t sit in streams often, change the oil and go. But in my case, the rear axle with LSD and changing the oil is not a very cheap task. And some gatherings in the water will already pay for the entire system. The principle of operation is simple, we supply 0.1-0.15 atm to the gearbox, the seals burst and water can no longer get into the gearbox.
Lech, what's the point of blowing the gearbox with air? The breathers are designed to relieve excess pressure and not overload the seals. And you're going to do the opposite. Or I don't understand something.
Regular breathers work in both directions. When the bridge cools (for example, we stand in water for a long time), the pressure drops.
