Meta M357T-V2 removal disaster - any help out there for an immobile bike?

[Extremepie]

Hi -


Well I did look around online and ended up with a youtube vid suggesting it was straightforward.  I've actually seen it linked to on here too.  Nothing suggested you could make a right cock-up of other bits during trial and error diagnosis, but a recent thread from someone else here who had their bike stolen suggests that it's entirely feasible to end up with a buggered 5EB-81950-20 relay unit and non functional neutral light / system along with a blown 20A fuse. I did blow the 20A signal fuse (now replaced)  but the neutral light has ceased to function.


Anyhow, feeling suitably chastened, here's the current state of things. 


Alarm has been cut off.  All wires to the back of the bike ignored for the time being.  Presume they just operate the flashers during arming / if the alarm is set off.


12V wire found and terminated.  Earth wire found and terminated.


So I have 4 left, all in the choc block as shown.  One of them has 4.9V when the ignition is on.  The others are showing 0V.  I have made jumpers to diagnose them BUT with the neutral now messed up and the start button seeming to have less spring than it did I don't know what needs fixed first.


I have a multimeter and I can use it.


I have removed the 5EB relay unit thinking that it may be feasible to hot wire the terminations to get past the alarm connections and then replace the relay afterwards but don't know what to jump to where to do that.


Any help much appreciated!
