Hello,

I am planning on installing two heated-seat setups shortly, and saw in a DIY that it connects to the 12v line for the cigarette lighter. Each seat can draw up to 5 Amps and so I wanted to make sure 1) Can the car's alternator and electrical system safely and consistently handle that, and 2) Is the fuse for the 12v line to the cigarette lighter at least 15A for a good over-head margin?

Other relevant details: Car has an Amplifier for the sound system installed by previous owner. Leads to battery have been upgraded to handle that better, from what he told me. Looks like a great setup. Alternator pulley and everything is stock.

Just want to make sure that my planned dual heated-seat setup wont cause any issues.

Any advice and input will be great!

Thanks guys

an extra 5-10A should not, but I would not run it from the lighter.

If memory serves, it's a 10A fuse. You should tap the spare ignition-powered lead in the fuse box area on the driver's side and install a switch. AND PUT A FUSE ON IT.

Thanks for the input. I guess the fuse box makes better sense. Any place I can get diagrams? Or is it all printed by the fuse box itself? I have a few days to do research before I plan on actually doing the job. The heater units come with switches, so that's taken care of. Adding fuses is definitely a smart idea.

I just finished my heated seats last week. Did both seats and ran a 12gauge lead from the fuse box (with an inline fuse) to behind the seats. Have a 30A relay controlled by the lighter there to switch them off with the ignition.
Electrical draw shouldn't be an issue for you

Great, glad to hear current draw should not be an issue.

But does anyone know what the 3 leads in the fuse box, lights, constant, and ignition, are rated for? What level fuses do they have? I've checked, per suggestion, by pulling fuse 23 in the under-dash fuse box, and 54 in the under-hood area, but neither affected the function of that circuit. So I'd just like to know, what did honda actually rate those three pins at, and which fuse is the appropriate one.

Thanks!
