OK...I believe the defi oil pressure sensor is a standard variety that has 3 pins on the connector: +5V, 0V and sensor out. You need to identify the sensor out - probably the white wire - and splice a wire to that one and take it to a spare input on your Syvecs. You may do well to splice a ground wire as well and connect this to sensor ground at the Syvecs, just to make sure the defi and Syvecs grounds are connected.
The oil temp sensor will have 2 wires - one will be grounded at the defi controller, the other will be connected to a pull-up resistor within the controller and you'll see the voltage vary with temperature.
You need to splice in to that wire and take it to a spare Syvecs input - you'll need to make sure you use an input that either has no pullup, or that you turn the pull-up off otherwise you'll mess up the Defi scaling.
The pressure sensor will have a linear voltage/pressure relationship, probably 0.5V=0Bar and 4.5V=10Bar and you will be able to get the Syvecs linearisation sorted easily.
The defi temp sensor you will have to characterise yourself as it will have a non-linear relationship. Basically, use SCal to monitor the input voltage and take a note of the voltage vs temperature on the Defi as the engine warms up and use that data to create your own linearisation curve.
Sounds more complex than it is...honest!

thanks for the instructions.
Ah...bit far for me then 
If you wanted to send me your defi leads, I could modify them for a small charge, if that helps? And if you were able to send me the sensors too, I could sort out Syvecs linearisations for them as well
