You could replace the CSV hose with a short stub, plugged with an 8mm bolt; just use any 8mm or 5/16" bolt that has an unthreaded section below the head. > Anyway.

You can check to see if this is the right CSV wire by measuring the voltage on it.

This means that the starter wiring is correct. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
