You remove the Phillips screw that holds the cable clamp, flip the clamp over, and slide the plastic cover out past where the clamp used to be. Then reach in the end and pull the plastic ECU connector straight out the end of the ECU, with all the wires attached. > B) I would be interested in getting a working head temp sensor.

This is the hard part about finding intermittent problems: You have to be able to look at just the right thing at just the right time in order to find them. > I'll try disconnecting the CSV in the meantime.

The actual switch point varied with the year. Russ believes that you don't really need it at ANY temp, but I prefer to leave them hooked up. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
