Hello ,

I am looking at installing a engine oil temp sensor that will be used directly to the ECU (no gauge) . I was wondering would it be better to use a bosch sensor with 2 wires or use a tempeture sensor with a single wire similar to a gauge sensor ? I have seen a lot of racers use the Bosch sensor but what is the benefit of the Bosch (2wires) over the single wire sensor ?

What would be the ideal way to run the wires to a link pnp ecu ?

Thank you!
