Talk Morgan Forums Thread Like Summary - No power to dash panel

2012 5 speeder I seem to have lost power to both dials on the dash board. No speedo, revs, info, no warning lights - absolute zip. Suspect the power supply connection. Fuse ok. Taken the fire wall out. Moving wires in the loom momentarily restores but I can’t find which particular wire or connecting block is the one. The published electrical diagram is pretty useless ( to me at least) does anybody which is the supply wire?
Just out of interest, in the absence of someone to watch the display for signs of life I’ve positioned my phone where I can see it and the camera can monitor the dash.

The 20 pin connector seems to cause quite a few issues, intermittent engine stops etc. Thanks for your input again Richard, I can never work out how you make sense of the wire diagram in the parts book....but you do.
