Adding the Homelink is doable. I was planning to add one to my Special Edition. I purchased a Crossfire Homelink off of ebay. The Homelink connector pin outs are on page 8W-80-66 of the 2004 service manual you can download from this site. Pin 1 is for the ignition switch B+ (12v), Pin 5 is for fused B+(12v), and pin 3 is ground. I connected the Homelink directly to the battery (bench type test) and successfully programmed it to operate my garage openers. Unlike other Chrysler products (as we know it was not built by Chrysler) the Crossfire does not have connectors and wires for accessories not sold with the car. That was also found out with installing fog lights and navigation radio. Anyway, you need to tap into the dome light wiring to power the homelink. The dome light connector pin outs are on page 8W-80-29 of the manual. Pin 2 is ground and pin 4 is the fused B+. I made a paper template to cut out a hole in the header trim.

Before I followed through with cutting the opening in the header one of my 15 year old door opener motors died. I saw a great sales/deal on Sears top of the line units, so I decided to replace both of my openers. After I installed them I suspected there could be an issue with the rolling code technology of the new garage openers which I confirmed. The Homelink would not work with the new openers. The Homelink on my daily driver would not work either. There was no value in it, so I abandoned the Crossfire Homelink project.

I have been using a regular opener control I would have to lock in the center console when the top was down. I discovered that Sears openers are made by Lift Master. Last week I purchased a Lift Master one button thumb size remote control which I'm going to attach to the Crossfire key.

I think it's a worthwhile project, but make sure the Homelink works with your garage openers before doing it.
