Do I install the heat pads under the original cloth?
You can, but it's alot more work, and makes the heat take longer to feel. We recommend adhering the heat pads directly to the Clazzio kit before installation (see pictures below). This is alot less work, and you can feel the heat much faster than if it has to go through 2 layers.

How hard is the kit to wire?
It's pretty simple, really... On the Universal Kits, there is one ground, and one positive lead for each seat. Simply join the 2 kits together, and run the black to a good solid ground, and run the red to a circuit that turns on and off with the key. A pretty common circuit to tap into is the cigarette lighter. In most vehicles, the amperage is high enough to run both seats on high without blowing a fuse, and they usually turn off with the key. On the vehicle specific kits, there is a Constant power, Switched Power, Illumination, and Ground.

Where do I install the switches?
With the Universal Heat Kits, you can put the switches anywhere you'd like. All you need to do is drill a .75" hole and pop the switch in. With the Toyota, Honda and Nissan Heat Kits, you will have little pop out squares in the dash you'd need to use. Sizes of switches are listed above.

Where do I hide the wires?
Every vehicle is different. The easiest is if your vehicle has a center console between the front seats, you can simply route the wires through that. If not, common places are either under the door sill, or under the carpet.
