Re: Expelling Heat
On 05 models and up you will only need one relay with an aftermarket alarm. These models have the express down button for all windows on the drivers side door, so you will only need one relay to activate that circuit.
On other years without the express down, I think a relay can be hooked up to all windows on the drivers side controls to make them go down however I do believe most installers like to use a seperate relay for each one.
As far as the key fob that came with the truck, you are out of luck unless you can find and installer that can make the panic work windows. This might get tricky though.
