What part number relay is best to use for this situation? Do you have a diagram available to explain how you connext to the lead going to the relay for ignition control?
The relays are readily available at Radioshack: 12V, SPST, 30A or 40A rated contacts; you could also use SPDT just don't wire the normally closed contacts. The ones with a little tab on them to screw mount to a bulkhead would work great.
Study the fuse block and put a meter on some of the fuses you'll figure out which ones are keyed to the ignition. You can buy an interposer that fits between a fuse and the fuse socket that lets you take a lead right off that and run it to your switches and then to the relay coil leads.
I really don't have a wiring diagram. What did your heated seat kits include by way of instructions? If you can follow it, the wires (-->) connect like this:
BatteryPos --> inline fuse (15A?) --> Relay Center Contact
Relay NO contact --> Seat Heater 12V
Relay NC contact --> insulated with heat shrink (not needed if SPST)
Switched 12V --> HeaterSwitch Center contact
HeaterSwitch NO contact --> Relay Coil positive Terminal
Relay Coil Negative Terminal --> Ground
Seat Heater Negative --> Ground
