Hi all,
I've just started the install of my VBG1 boost gauge, and I'm glad I grabbed a spare vent from a wrecker.
It seems the vents in the US models are slightly different to ours, with the horizontal louvres being held captive in a hole well inside the vent plastic in the US, but "clipped in" at the edge on AUDM models.
I've had to modify the holes slightly (widen them) to have the gauge sit properly.
The other thing I've noticed is the top of our vents look different to the US models, and the spot where the VBG1 instructions say the ribbon cable should exit doesn't seem to work for us. I'd be keen to know where others have run the ribbon cable out of the vent into the under-dash area.
Next step is to get power to the control module, and a boost signal from under the bonnet. I grabbed the tubing the VBG1 guys sell, I just need to find a good way to route it now.
