This is a simple walkthrough for how to change one of your cigar outlets to be a switched outlet. The reason you may want to do this is in case you leave something plugged in at all times and don't want to worry about battery drain. I'm sure there are other useful applications as well.

Step 2. Locate wiring from back of cigar lighter plug

Step 3. Connect a lead from either fuse 29 in the rear fuse box or from the switched power on an aftermarket stereo plug (if you have one) and run it to the dash opening where the cigar wiring is.
