Simon Posted June 29, 2016 Report Share Posted June 29, 2016 One of those wires will have a variable voltage. You can tee off this wire and put it to a AN volt input.You will then have to measure the voltage vs pressure and enter a custom calibration in to the ECU. (I'm assuming that the sender unit operates a bit like a temp sensor and gives a varying resistance) Quote Link to comment Share on other sites More sharing options...
