Hi Guys,

Has any one tried to connect 2 wire (vdo-style) sensors in parallel?
Is there a wiring diagram available?
I want to connect my VDO fuel pressure probe, as well as my fuel level sender, on both the DL1 and the respective instruments.
Is it still needed to use an external power source?Does it have to be one of the 5v dl1 outputs, or i can use 12v from the car?

Thanks
