place to buy parts for dei alarms?

I bought a Clifford 50.7x alarm/remote start at my previous employer. Unfortunately, I bought this alarm (at a significant discount), during our liquidation, as the company went out of business (Ultimate Electronics). Upon trying to install the alarm, long after our stores all closed, I discovered that someone had opened it, and taken 2 key harnesses out of the box. I'm missing the cord that goes between the brain and the antenna (it has one in the box, but it's the wrong one, it's the one with 3 plugs on one end, antenna, valet switch and led, I need the one where this is all on one 6 pin plug), and it's missing the H2 18-pin harness. Does anybody know of a place where I could find just these parts? I checked in our spare parts at work, and we don't have anything, and I looked on ebay to no avail, and unless you are a dealer, Directed has made it nearly impossible to actually contact them for any type of support. Or, is there any shot that anybody on the forums has these parts lying around that I could buy from you, hopefully on the cheap?? Thanks

An authorised dealer should be able to supply the parts. With the H2 harness you won't need all of them, why not just solder directly the ones you need.
