Dometic power Channel Awning Accessories??

Thanks to the folks above. I FINALLY figured it out! Well, it's not like the web site or the information pages describe at all. My awning does not have that wide track, but I found it fit here, and actually found the light switch inside the camper that turns it on. Sheesh! What a mystery:





This looks like the add on track that can be placed anywhere. Too bad the awning roller itself it's the one shown on Dometic's web site though!

Thanks for your help everyone!
