In Dash Rev counter not working.
 

Ok the bike has had this problem a while now and i'm not getting far with it.

Earlier in the year a few connector blocks failed on me, and since them i've lost the rev counter in DIAG mode, when i bring it up i'm just getting a static "0" if i plug the PC5 into the laptop i can view it in there but that isn't always practical.

can anyone help me with which wire i'm looking for from the ecu to the dash and where it's routed, and also if it's direct of goes through any other items on the bike?

cheers
