Well, yes, Bob, if you want to keep the ashtray open all the time.

However, some accessory plugs will not fit in the confined space in the ashtray in front of the lighter receptacle. Keeping the ashtray open tends to negate the use of the recessed tray underneath it, too.
I have found out that although the lighter receptacle IS switched through the ignition, the second receptacle in the console compartment is NOT. Considering that the one in the console is typically used for accessories that you want to keep plugged in while NOT running down your battery, the fact is is not switched makes little sense. For right now, I have to manually shut off my XM receiver each time I get out of the car.
So, I'll ask a second question: Anyone know how to remove that receptacle so I can get to the wires? I want to to run a second wire to it from the Lighter fuse so it will become switched, too. I'm not one to go prying around with a screwdriver and scratching things up needlessly. Anyone know the secret?
