Hello, looking for assistance installing a VDO fuel gauge. I am hoping someone has installed one and knows what wires connect to what terminals. Attached photo. There are two terminals and I assume these connect to the fuel sender. There is also a red/white/black set of wires. Any assistance would be great.

S = sensor
- = ground + = hot wire The other 2 posts look to be a light ? Flip the gauge over and take a pic. Are you sure that the gauge will work with your fuel tank sensor? I take this is a GT style fuel gauge? |

I found this doing a search, so maybe I need to get the correct gauge:
Posted from LarryM: here is the info from 2004 for correct gauge "here is the answer via VDO Support: Use VDO Part Number 301 020 with the OEM 914 fuel sender; (spec'd for Beetle O.E. sender or VDO 221012 sender): 73 - 10 Ohms, "Fuel" The reading will be off slightly but will not be noticeable William M.

I was looking at the existing stock wiring to the fuel gauge and it shows
Ground Green 2 red/white stripe + What is the red/white stripe wire? I assume Green is from the sending unit |

So, the Red/White would go to the + terminal on the gauge, the Green to the S on the gauge and the brown to the - on the gauge? |
