Hello, I've recently acquired a W124 with a 606NA which I'm loving! I've already sorted a few little issues but yesterday I tackled changing the glow plugs, thankfully they came out no problem. It's not back together yet as I need to get the glow plugs and some of the crank breather hose connections need replacing, arriving Wednesday hopefully. However, someone had been there before me and messed with the electrical connections to the vacuum valves attached to the underside of the inlet manifold. The insulation had crumbled. I've repaired these with some self amalgamating tape and heat shrink tube and re soldering but I'm not too sure about which wire goes where now. I'm not convinced any of the butterfly valves were working. Would anyone have a schematic, or photo of the the valves and the vacuum lines please? Thanks.
