I have a factory alarm and want to add a remote start and window roll-up and keep my existing remote entry system.
I have searched around as to what I need and what type to get the job done but no luck. remote start, what kind and type and t-harness and some passive alarm block. anyone with any info.
Thanks B

The add on remote start part is readily available, something like the Valet 561T. The window roll up module would be the tough part to add with this system as you want to retain your factory remotes and the factory system does not offer any type of extra output to control the windows. I would suggest a complete system that offers the additional outputs required to do what you want to do. When you install an after market system it does not disable any of the factory components, it works in conjunction with them.
