Thanks for that info Bill. I did not realize what changes have been made.
I would want to retain the blue box, as it is far simpler for us Amelians who have factory systems. Converting to relays and all the associated wiring would not be much fun.
Fortunately, I have had not issues with it, other than I had to go to a 3A fuse vs 2A. The 2A kept blowing unexpectedly - maybe an age thing there as the systems start to draw more current.
