Wiring for '01 C1500 / '03 Intrepid

I have bought an aftermarket alarm for my 2001 Chevy C1500. It only has remote start and keyless entry. I also have bought an Alarm, remote start and keyless entry for my 2003 Dodge Intrepid. My problem is that they sent instructions for the wires on the alarm but nothing for my vehicles. Is there a place to find this information. Such info needed is what color wire does what, (in my vehicles) so that I know where to tie each wire from the alarm. Any help would be great.

Thanks,

I have been reading some other messages within this forum and see I may need to give more info. I am about to install my first alarms in these 2 vehicles. The '03 Dodge Intreped SE has no alarm istalled from the factory. So this should be pretty basic???? My '01 Chevy Silverado has the factory keyless entry and panic only installed. Is there something I need to do to this during the install of my new equipment. The new alarm equipment being installed is from Accele. Thanks in advance for any and all help.
