Fuel level sender wiring
I have a VDO fuel gauge and sender. The both came without instructions. The gauge has terminals for the lamp - easy, plus 3 others, labled +, - and
S. 12V, ground and signal I should think. The fuel gauge is just a variable resistor with 2 terminals. Should this connect to 12V or ground?

senders are pretty much always relative to ground.

+ is 12v ignition on supply.
- is earth.
S is to one terminal on sender.
Other sender terminal is to earth.

Plug the gauge into 12V (+ terminal) and ground (- terminal). Leave the signal terminal unconnected. Then measure the voltage on the signal terminal
with respect to ground. If it reads 12V then I believe you should connect the signal terminal to your sensor, and the other side of the sensor to
ground.
