I found a solution which worked for my H3. After a great deal of research and digging through dealership parts shelves... I finally found that the 2009 to 2014 Tahoe/Escalade sunroof drive ribbon cable matches my 2008 H3. Even the carriage arms are the same. I think prior years of Tahoe and Escalade must have used the old style steel cables. There are some models of newer style Lexus/Toyota which are also the same, and I know folks who have used a Lexus motor to successfully replace their damaged H3 sunroof motor. I was fortunate today to find a new 2009 to 2014 Tahoe/Escalade "ribbon cable drive replacement" which only comes in pairs and includes the new sunroof carriage arms as well. I found it on eBay for $100. I don't need the carriage arms, but I can easily unsnap the ribbon cables and slide them into my track and resnap my existing components to it. Good luck. Go save some money and stay dry!
I am not sure how long these will be available, he had 36 of them from where he had bought out a closeout of the complete sunroof assemblies and he was breaking down the parts to sell individually. But dig around, the GM new style is the same as used on the H3, the Lexus/Toyota appears to be also... none sell separately from the dealership, but by digging around on line and through salvage yards the parts are much less expensive for the Lexus/Toyota/GM parts where there are a glut of cars... as opposed to the limited supply of the H3 available.
I posted a thread in the H3 forum regarding the H3 sunroof cable ribbon alternative solution.
