MMU2.0 with MK2.5

Has anyone connected MMU2.0 to a MK2.5? The installation manual only showed how to connect the power and signal connectors to the new MK3 board. I improvised the MMU2.0 power connectors to the PSU power connectors on the board, and connected the signal connector to the only 5 pins left on the board. The MMU powered up and initialized, but gives a constant noise. The printer also does not recognize the MMU.

You are brave...

Idk maybe reverse the connector? ( No liability ) just a suggestion since you are a brave one.

Maybe you'll have move the pins in the connector. Best to get official answer..

I think the MMU power connectors are connected to the PSU connectors on the MK3 boards, so I figured it's probably OK. Signal connectors won't damage the board at least. I tried to reverse the connector, but the printer won't even boot up and gave me a blank screen on the LCD. So I think the signal connector pins have to be re arranged somehow for the MK2.5 board.
