Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

I was told that the 791 can controll the rear defrost but the wire was never hooked up...I would like to k now which wire I should use from the alarm. Also how do I control this output?

the 791 has two options for activating the rear defroster. In the 5-pin H3 harness, the blue/white wire is a status output that outputs a negative whenever the remote start is running. The other option is to use your AUX channel 4 or 5, and set it to a latched output.
