2004 buick rainier heated seats , defrost

To anyone that can help I have a 2004 Buick Rainier and I am trying to hook up the heated seats and rear defrost to a remote start(APS-997a) If anyone knows the location and colors of these wires please help me out. I just really don't feel like testing the wires. And also do you know if the rear defrost or the heated seats need a relay on them?Everyone need a little help sometimes

Oh and also I am using the 1700g1 bypass and wanted to know if anyone new if that unit had the option to activate the heated seats and the rear defrost if the temp in the car was below 32 degrees?Everyone need a little help sometimes
