Meglio 200, the £700 car thats now 5k deep and still incomplete

They need plumbing into the manifold somehow.
I think the megane engine has a one way valve in the pipe so you don’t end up with boot pressure in the servo

Left hand one on your diagram should be going to a carbon canister solenoid down the drivers side of the engine. You can throw that in the bin.

Right hand one is the brake booster vacuum feed, hook this up to the engine in some way. Dont worry about a 1 way valve, the Clio already has this on the brake booster connection.
