Actually, the Battery Saver was the 2nd item I purchased for my Delorean, after the Fanzilla. It installed easily, quickly, and works well. I mentioned the Volvo switch because people were talking about designing a new door switch, and that feature was one thing I found to be very useful and user-friendly. Even if I did have door switches that had this feature, the Battery Saver would still be useful if I had the trunk or hood open. Dave vin 16367 [Non-text portions of this message have been removed]
