Ok, I’m not able to help further sorry, I don’t have the 360 system so unsure how that could impact things, but it could be a harness power wiring issue, but I’m sure someone will be able to advise if it could be related.
If you don’t get a response here, you could also try the telegram group I via the DUDU7 channel or possibly if it’s a wiring issue, the HW Installation Support channel.
