"VDO" WIRING

[legsroses]

Hi
I need know colored wires from which depend following functions:
- fuel level, engine problems: inside left side "VDO" instrument
- rpm, N: inside other side "VDO" instrument
Good Weekend, bye bye

thanks for your reply.. is it ok for 2010 roadster too..

Sorry - donẗ know - contact @DEcosse

don't worry, thanks ;-)

Those all come from the CANBUS datalines (Red & Blue)

Are they not working or are you trying to swap out gauges with non-std or ???

thanks DEcosse.. let me know a premise, I use and aftermarket speedometer but I keep our "VDO" (hiding) otherwise engine is impossible.. so I removed, soon after, tachometer too and since then I never used it (nor replaced it with anyone)..

that said, now I would like mount and aftermarket tachometer (in this case that built by mmb-messtecnick, same brand of my speedometer)..

now, problem is this one.. I dont' know how I should connect "mmb" wires with those of original system (namely "vdo" wires).. in other words, I need understand which wires (color of each one wire, then of each one function) I need in order that working all normally.. for example: I put a new indicator for neutral gear, what I should do if I want that it lights up.. namely, which is wire (wiring of our right "VDO" dashborad) I must use..

Thanks in advance

There is no discrete signal for rpm at the instruments - you would have to use the drive signal to one of the coils for your rpm source
Neutral is Black/White wire and Low Oil Pressure is White/Brown
Green/Red on pin 7 (NOT to be confused with Green/Red on pins 3 & 4) and Green/White on pin 8 are the turn signals
White/Blue is for High Beam

You cannot get signals for Fuel Level or Engine Light as these are encoded digitally from the ECU on the CANBUS

so I will not be resolved anything regardless, or maybe if I will buy a "VDO" (used tachometer) I could know signals for fuel level and engine light.. I mean if using "VDO (tachometer) a car electrician, doing some technical checks, could solve.. I would not know, I don't know almost none of these thing, but maybe he could measuring with oscillometer or detect absorption with the ammeter.. thanks again

Let me try again .......
There is no independent wiring for those signals - they are integrated into a coded data stream that is then decoded by the VDO meter internally.
