I decided that we would be better off with a dual USB plug in the glovebox instead of the old cigar lighter style. I normally leave my IPhone in the pocket plugged in and I can now charge another device at the same time without having to use one of those plug in USB adapters.
This setup came with the proper plug and play so I just plugged into the factory connector after mounting the plug in a hole I drilled in the pocket as per the directions.
It works great and was only $23.00
