Keyless entry Install help

Hi, I hope someone on here can help me. I bought a keyless entry with trunk release from ebay and want to install it. I have scoured the posts to find some detailed instructions on how to do this and have found some bits and pieces that have helped. I guess my question is, is there anyone who could give me a step by step or direct me to one. I have never done anything like this before but would like to learn. My car is a 2001 alero with no factory keyless entry installed. Thanks in advance for any help anyone can provide.

This came as an option on the car (a FOB and trunk release). Wouldn't it been easier to just get your parts from a junkyard?

It's really only one part (the RCDLR) and the remotes. It hooks up with 3 wires (power, ground, class 2).

But.. The wiring is different in the cars with no RKE (no separate driver unlock relay), as well as if you did retrofit it, the BCM would have to have the options reconfigured.
