This signal is in the green connector (user port). Pin #4. Forth conenction, counting from the gauge side. You can get RJ45 plug and make you own logging connection.
The sensor voltage is as following:
- standby ........... ~0.5V
- span ........... 0.6 to 4.5V
you will priobably only read a sopan of 0.6- 3.5V because the signal is conditioned by the "SC" to display ~5-6 bar on the gauge.
Alternatively, It is possible to read the "RAW" signal but it will be in "pulsed" form. You have to use a "frequency" input on your logger. Also requires soldering work.

Richard I just did this and had some weirdness -
I have a CAT5 cable with this pinout:
I am using the BLUE wire (positing 4 in the connector). When I hooked that up to an Analog input on my ECU, the gauge had full bars lit on the gauge with the engine off but ECU/etc on. I unplugged the cable from the USER port and the bars went off.
Is this not correct?
