AAW mopar kit vs. Highway 22

I tried calling AAW but their offices are closed so I will ask the question here. The mopar kit is 1000, the highway 22 kit is 550. Besides keeping the mopar wiring colors what makes the mopar kit worth the extra 500?? Has anyone installed either? Thanks for any advice and help!

I am also looking for a new wiring harness. And was also wandering the same question. If I look at other "universal" mopar ones. Is it worth the extra 500,-?
