Seat heaters durango

I had a installer install a viper 650 in my 2001 Dodge Durango. I had him hook up my rear defogger and drivers seat heater to a aux output{remote controlled}. Needless to say to car battery died 3hrs after it was done. I unhooked the relay he used and no more problems with the battery.

What I would like to do is get the drivers seat heater to work. The switch is a high low toggle style. He wired it to under the seat. Doe's anyone have or know of the wiring of this vechicle?

Thank you all for any help.
