Newb can't get it working...please help!

Hardware: MBP (mid-2015, Retina), Sonnet Breakaway 350w, AMD Radeon RX 580, Apple TB3-->TB2 adapter cable and Apple TB2 cable

System: Mojave (10.14.2), purge-wrangler 5.1.1 with Legacy AMD eGPU's/Ti82 devices/TB1/2 AMD eGPU's enabled

Problem:  I can't get the Breakaway recognized/powered by the MBP.  After running purge-wrangler, plugging in the Breakaway, rebooting twice, logging out and back into Mojave -- still nothing.  I then uninstalled purge-wrangler and tried automate-eGPU EFI -- same result.  

I've successfully used the Breakaway with a Mac mini 2018 and a TB3 cable.  What else could I be missing?  I can't imagine either the TB3-->TB2 adapter or the TB2 male-male cable from Apple are faulty, but I'm scratching my head trying to figure this out.  

Thanks in advance!

Does the enclosure show up in System Information - Thunderbolt tree? If you don't see anything in there, it's a hardware issue with either the Thunderbolt 2 cable or the adapter.
