Adding auxillary power socket
Hey all. I'm in need of adding additional power for my sat radio, etc.
I have been thinking of where the best place to draw clean power from.I have tried the stock lighter socket but it puts out a helluva lot of alternator whine. I was thinking of tapping the switched powee line from the radio as it producs no whine. Any recomendations?
