Another MPG question for Masso

There are a few other 15 pin MPG’s on the market and curious if anyone looked in to one of those and which wiring to change out to make work? I did read that the 15 pin from Amazon or Ebay are 5 volt so one thing that would be need is a voltage reducer in line would work? The ones I looked at are Rat Rig’ however my best guess is that they all come off the same production line!
Thanks for any input!!

If you have a Masso controller…
