Seat heater wiring help

Here is what I'm working with.


I have 2 of these harnesses for my seats. One for the driver side and one for pax. Both come with a relay and a seperate inline fuse that is not connected. I want to run these off my cig lighter. Can I just splice both hot wires for each harness together then connect to the power wire on the back of the cig lighter? Do I need an inline fuse for this? The directions recommend tapping something that can handle 10amps, can the cig lighter handle 20? Also if you know which wire is power for an 09 jku let me know. Thanks.

I tested my heaters on multi-meter before I installed and they pulled less than 2 amps each on low and slightly less than 4 amps on high. So total amps combined is 8...round to 10.

Not sure if that helps you. I don't know what you can pull through the cig lighter but look to see what fuse serves it and see what size fuse it is, that should tell you.

Tie both red leads together and use a single fuse, 10a should fuse should be fine. Ground both black wires either together or apart, whatever you want to do there. Use the right side cig lighter, since it turns off when the key is off and the door is opened.

What he said, but I'd test whatever cig lighter you use to ensure it only works with key-on.
