That's the neutral switch wire and the 2nd/3rd gear signal to the ECU. Engine will run without them.

Sid, why would they be spliced in 1st place, common practice,performance mod? also would it still show neutral on dash?

Thanks

The two that are disconnected need not be spliced, (but it doesn't matter if they are), they are the 2nd/3rd gear signal to the the ECU, and are removed to inhibit the ignition retard that made a Curvy pass the then current noise test, blue wire goes to the neutral light.

Appreciate your time, sorry for being a bit vague earlier.
Thanks again.

Did this make the ECU restrict 2nd & 3rd ??

Don't get how it helped with noise

Restrict no, retards the timing a dab at certain revs in the two relevant gears as a means of ever-so-slightly depressing power output and thus reducing noise a bit so that the bike would pass the then current noise test.

Back again,SS, do you recommend connecting as per original block if mot spec no longer applies?
