Here's an electrical question for ya David. When fitting a heated oxygen sensor to a vanagon that had just a non-heated single wire one, what is the proper place to connect the heater wire to ? - the wire that will power the heating element in the sensor. I have my solution, and it's working fine - just wonder what you would recommend. Partly why I even thought about this much , is ..........I think it was on this group - Neil with the ABA 2.0 inline four, powered his off the ignition circuit, and there was suspicion that that was causing a problem . thanks, Scott ----- Original Message ----- From: "David Beierl" <dbeierl@ATTGLOBAL.NET> To: <vanagon@GERRY.VANAGON.COM> Sent: Thursday, September 10, 2009 12:22 PM Subject: Re: O2 Sensor wire connection (wiring harness end - 2.1)
