Thanks Bob,

I can verify that the curre= nt draw listed in Bobs post is about right. =C2=A0I have seen seats costing= $150 each, but the link in my first post was to Amazon, 2 seats for $45 wi= th free shipping.. =C2=A0those are the ones I have. =C2=A0

Here is the product descrip= tion from the web site.=C2=A0 3-5 amps.

=C2=A0=

Carbon Fiber technology, heats up in secon= ds with even heat distribution

3 Year Warranty for the heat pads. 1 Year Warranty for the Electric parts.<= br>
Deluxe illuminated Dual Temperature High/Off/Low Round Switch

Dual Temperature Control System Electronic thermostat (built into each pad)= regulates the electricity / temperature circulating within the carbon fibe= r seat heating pad. This system regulates the flow of power and maintains a= narrower temperature range whether in a high or low setting.

Example: The high setting will have a constant range between 140=C2=B0F to = 145=C2=B0F. The low setting ranges between 120=C2=B0F to 125=C2=B0F. These = respective temperatures are maintained at these respective levels.

Included in the wiring harness is a relay that controls the power / tempera= ture of the heating pads from high to low with an in-line fuse. Backrest &a= mp; Seat Bottom Heating Pads -- 18" x 11" Pads are approximately = 1/32" thick. Either pad can be installed in back or bottom.

Electrical Specs Wattage: 24~36 Watts per= Pad, 48~60 Watts per seat Current Draw: 3 Amps on Low Heat Setting and 5 A= mps on High Setting per Seat. It is a 12 V system
