... I found a plug hanging down below the battery that accepts the plug from the lighter wiring harness. When I checked this with the meter, the polarity was reversed. It also reads in the lower 11 to high 10 volt range. It is powered off the ignition, (switch has to be on run, and will not power up in accessories).
I would like to use this plug if possible. The only thing I would be running is a GPS and occasionally a cell phone to charge. Talked to the dealer but they won't give any info unless I make an appointment and $$$. Any advice will be greatly appreciated. Can I use that plug or should I just run it off the battery with an in line fuse?
