2 part question here.
First, I have an Ultrex with the US2 system (non mega, built in, round ducer). I have a G1 Helix 10 that I'm debating swapping my Helix 7 Mdi for. I called HB and they said I needed this ducer for the G1 10:
XTM-9-WIDE-DI-20-T
If I end up using the 10, will that built in ducer in my Ultrex work with the 10?
Second part; to clean things up that I wasn't using (cable management), I removed one cable from the Ultrex and tucked the other inside the head unit (one could be removed, the other was sealed in and cannot be removed). Which cable is which? Meaning, what does the cable that I could not remove go to? I believe the one I did remove (threaded coupler on each end) would go to the Helix, yes?
