05accord sunroof and window wiring

I traded my 2004 civic in for an 05 accord ex v6 coupe automatic with leather.
Im installing a Mannix SM700 two way fm remote start /alarm system.
I want to close the windows and sunroof using the mannix remote transmitter and leave factory window rolldown features intact.
Im not able to run 8 high current conductors into my drivers door. So I want to utilize the factory key/switch window roll features available in the drivers door. I am able to run two smaller signal wires into the drivers door. I can easily get to the sunroof switch.
Anybody ever do this or know how to go about figuring it out?
