connected the sender from my LPG tank to my regular gasgauge.
closed the dash again.
the new Tach is bottom left. And my LPG tank seems to have the same sender (0-90ohm) as my original gastank, because I just filled her up and she now also shows F (full).
now these lights dont work anymore :
- high beam
- handbrake
- 4WD
well, thats for next weekend.
