Booster hose delete

[anaphe]

Hi Gang,

My s54 swap is going in an e30 m3 sans booster (Tilton dual).

Where can I cap this line? Can take it off of the vacuum manifold at the back of the head or should I leave it and cap it at the end of the hose?

The reason is ask is that there is some electrical harness attached looks like an IDle control valve or something similar and I don't want it to affect something else .

Thanks for the help.....on to the DBW pedal today!

You must have an 05 or newer S54 with the vent hose that has a valve? See if you can replace it with the older style hose. Then just plug the open ports with rubber caps.

If you cap the end of it, it would seem to be the same as simply plugging it. I removed mine and simply plugged each of the nipples on the intake manifold.
