Hello,
I have the autopage C3 RS-727, not the newer C3 RS-727A. It has been installed on my 2000 Chevy Monte Carlo for about a year or two now. Im having trouble finding the installation manual for the C3 RS-727. Just the basic functions were installed: remote start, door lock/unlock, and trunk release. I have installed a StreetGlow under body kit on my car and am wanting to control it via remote, but since i cannot find the install manual im not sure what the differences are between the C3 RS-727 and the C3 RS-727A. if anybody has this info, please reply
Thank you.
For anybody that is interested, I found out that the installation guide for Autopage Rs-727 worked out for me. The BLACK/ Green wire from the H20 pin is the C4 output (push lock + trunk button at same time), through which charges a 200mA ground signal upon button sequence. To change the factory output from a pulsed singnal, it needs to be programmed to make the output a constant ground until button sequence is repeated. 
This is the diagram I made up in order to hook up my neons to be triggered through my autopage remote and through a toggle switch, that way i can be sure to have them off while I am driving, and not have to worry; and to be able to easily turn them on from inside the car, (my very first diagram using SmartDraw, not perfect but give me a break!)
