Need a 12v switched source for seat heaters.

Just installed a seat heater for a friend as a xmas present for his wife. I figured I would use the radio power since that comes on when the acc is on but I either tapped the wrong power wire or the radio power is constant. Where would you guys wire the power for the seat so that when the ignition is off, the seat heater is not powered?

Thanks for any help guys.

Put a relay in controlled off the ignition circuit and powered directly from the fuse block. Done!

I ended up using one of these: http://www.autozone.com/autozone/ac...M-fuse-tap/_/N-25gq?itemIdentifier=32416_0_0_

Then used the sunroof fuse and it works like it should.

Thanks for the reply!
