A little update about the Koso's RX2N meter I am using.
After 2 units' that gives same defect , EOBD and OIL light flushing after several days without been connected to the bike wiring at all and the problem with non properly working tachometer on V-Max 1200 .
The guys from Koso Taiwan send me third up grated meter RX2N+ (plus) with different CPU and software , finally RPM working fine no issues at all.
here is a poor video of moment after I connect it :

and one after the bike was assembled :

I still have not connect the Oil and EOBD lights ( the orange and violet wires on first video that are issolated at the end ) these two red lights are still on the genuine dash board .
This is because the Koso meter needs a negative signal to it Oil ware
and since v-Max don't have EOBD light I want to connect there fuel warning light but I am not shore how to do this and I don't want to damage the unit during some experiments .
Can some body from here that is well familiar with max wiring and way of working to these two lights help me find a solution.
here is Koso's wiring installation instruction :

and here is v-max wiring diagram, I out some colors on top of it :

The point is that Koso needs Negative for it oil light and a positive for EOBD light.
I want to connect max's fuel light to Koso EOBD light but because of the other time they flashing , when starting the engine a am litle confused to which wire to connect Koso's wires .
I think I will have to remove genuine bulbs from genuine dash to prevent errors like wneh connecting the turn signals - with genuine bulb , Koso meter was showing both sides no meter wish turn signal is on .
