Remote Start installation question

[Millerad1651]

I'm finally getting my remote start installed today. It has the keyless entry already, so that will be included. If I ask the guy to make it so the back window can go down/up, is that possible. I don't know, and my guess is he'll tell me it isn't just so he doesn't have to do any extra work. I know the factory remotes on 99+ can, but I have a 98 and don't know if its possible. Here is the unit that I am getting installed. Thanks for any info.

Did you get your manual on this remote?

I don't have the manual. It was a gift for Christmas, and it was a groupon. The installer has the unit, and I'm am heading over there at 11 this morning. I've tried to look up whether or not it can be done. Other vehicles it can release the truck, so I don't see why the installer can't wire in to the back window switch.

You need to buy and add the DEI Window Module, either the 529T or 530T.

Ok thanks. I may just buy the 529T myself and add it later. I asked the installer about it and he was going to charge me $150 extra to do it.
