Aftermarket keyless entry

I have a 96 Blazer LS wiht power locks but no keyless entry. I bought a keyless entry,alram, and remoter start for it but I am having some diffuculties. Can anyone tell me where and what color the wires are for the +and - door trigger input. And also if I need to but arelay for the horn. Thanks if anyone has an idea hwere I can get a whole wiring diagram for my blazer let em know.

There was a post on this site about using the bulldog security website for wiring diagrams. I don't remember the exact address just look through the old posts. If that won't work I have the diagram 01 but I don't have any idea if they are the same.
