FZ8 doesn't start - multiple fault codes

My FZ8 SA 2012 will not start... it's cranking but doesn't fire. First the fault code was 12, crankshaft sensor defect, I did a check on the sensor with an ohm meter: it gave the correct value. I disconnected the bike from the battery for 10 mins, but when reconnected and trying to start the display now shows more errors: 12, 20, 30, 41. Where should I look now?

I managed to isolate the issue down to the wires, somewhere underneat the gastank. When I juggle around the big backbone under the gastank sometimes the errors disappear and then I can start the bike. I already disconnected al the connectors underneat the gastank, nothing strange to see... I also cut open some part of the backbone, nothing to see there.... what could be the next step?

If you don’t know how to find the wires and repairs them then maybe a new wire harness would be the easiest option.
