Hi all!

I have a Viper 5701 installed in my 2011 Jeep liberty, but the "remote start defrost" function was never hooked up (or is possibly unsupported with my setup?)

I was wondering if anyone knows how I could go about hooking this feature up so the truck's defrost will kick in when I remote start it (and it's below whatever the cutoff temp is)?

The option is enabled on the Viper (I purchased a BitWriter so I could program the alarm without using the all-too-exciting "push the valet button and count the beeps" method) and I'm fairly familiar with the 5701 as I've reprogrammed it several times after I upgraded it with the antenna from a 5901 to increase the range)
Just not sure exactly what to hook the "defroster" wire from the Viper up to. I have a "toggle" switch in the Jeep for the defrost, but I assume I would somehow need to involve a relay of some kind that will allow me to turn the defroster on from the Viper and still allow it to be turned on manually with the switch.

Thanks everyone!

P.S. Also, the temp sensor in the 5701 is way off - reads like 15-20 too high. I think I've heard that these are notoriously inaccurate but I just thought I'd check with ya'all
