DIY KEYLESS ENTRY on Power Liftback?

[TC-LIFTBACK]

I know that alot of people on the forum are stating that Circuit City does a bang up job on install on Keyless Entry for 99 buxs, however...

I figure I can save 50 bones or so to spend on other mods, buy a kit off ebay, have a fun DIY project to grapple with, and then have keyless entry to boot.

Has anybody done the install themselves?
If so, what kit did you use?
Where did you buy it?
How did the install go?

Thanks guys in advanced.
