    Default Hardwiring seat heaters

    I currently have a couple heated seat pads hooked up to a splitter and powered by the console cigarette lighter. But since the console outlet is always powered, leaving the switch on causes parasitic drain on the battery (adds about .60mA).

    What I'd like to do is hardwire them with a relay and actual switch buttons in the dash, but not sure where to draw the power from. I've already fuse-tapped the hazard fuse (footwell LEDs) and the cigar fuse (dash cam).

    Seat pads are each 12V, usually with an in-line 10A fuse. Since my car was originally a GX, the 30A seat heater slot of the fuse box is blank.

    You could always just take power from the power outlet at the front of the shifter instead of in the console arm rest? Thatís how Iíve always gotten power for my dash cam and phone charger. Just spliced into the connector at the front.

    Yeah the reason I went into the console arm was so I could keep most of the wiring hidden. Didn't realize the outlet switch would keep the current alive when the car was off. Is it as simple as tapping into a positive and negative wire? How do you access the front outlet wiring?
