Folks. Throwing myself at your mercy here. I own an 03 ST170 5Dr which I am delighted with. Except one thing.. The vehicle has two cigar lighter sockets. One mounted on the dash and one on the rear of the centre console for rear seat passengers. And they're both CONSTANTLY LIVE! I have an iPod dock which transmits on a set FM frequency. It's fitted correctly but owing to the cigar lighters being constantly live, drains my battery in a matter of days. Is there an easy and safe way to fit a switch to this circuit so that I can choose when to power up the lighter sockets. OR, is there a way to link the cigar lighter sockets to the ignition circuit so that they only come on when I turn the key? Of course, I CAN just unplug everything but this is becoming a pain in the backside and is loosening the plugs and sockets. Thanks in anticipation. KD.
