From BigBadBen as posted on bmwtips, here are the DME connections for the dual output O2 sensor simulator from www.o2simulator.com:
"For those that want to know what to wire for an ME 7.2, here are the pins/wire colours. 540iA Build 06/2000
Connector 2 on the main DME
O2 Signal Pin 17 Black and Blue
O2 Signal Pin 14 Black/white in my case, it should have been black
O2 Signal ground Pin 11 Yellow/blue
O2 Signal ground Pin 8 Yellow
O2 +12 VDC Large green wire near DME"
This was for a 540, but I think the connections may be the same. You should only need the two signal wires and the +12v and a ground."
