Hello from Finland and sorry about if this kind of problem has already dicussed but i didnt find any for solving my problem.

So i have installed Koso DB-01RN to triumph, and first problem was already there, no RPM signal to the meter.
Koso brown/red wire is the RPM wire and i have installed it to bikes harnes red wire but no, i have tried almost all setting which i can, but no RPM.
Do i have to connect it straight to the coil wire?

Edit: tester shows RPM from OBD

best regards
