The Bentley diagram shows the harness with the CSV option. If you delete all the wires #30-36, and the relay, valve, and temp switch from that diagram then you have your harness. I'd put money on the fact that your engine was replaced with a later engine by someone who wasn't quite sure what he was doing, so he left the temp switch from the later engine in place when he switched the rest of the parts over. It was a natural place to install the wire who's proper destination he had forgotten. You should just remove the temp switch, and run the wire to the solenoid terminal that is hot ONLY while the starter is energized. This may actually improve your gas mileage. There are some holes in the "firewall" above and in front of the engine. Install a rubber grommet in one of them and run the wire thru that. You don't want that wire to chafe and short out. There were several different temp switches. If you send us your engine # and the part # from the temp switch, I can probably tell you whether they originally came together. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Search old messages on the Web!
