Hiya Guys,

I got 4 new analogue gauges for my car (I prefer the look) and need some wiring diagrams for them.
I plan to connect them to existing sensors rather than installing new sensors in different locations. As that makes more sense than drilling holes and tapping everywhere.

Car - 2009 Audi S3 8P 3 Door
Engine - CDLA

Gauges -
- Wideband Fuel/Air Ratio
- Boost Gauge
- Oil Pressure
- Oil Temperature

I mainly need wiring diagrams for the following -
- Lambda sensor before the cat
- Oil Pressure Switch
- Oil Temperature Sensor
- ECU Pinout to each sensor

I need the pinouts for each plug to these sensors so I know which wire to tap into.
I wont be powering the gauges of these cables as they have their own dedicated fuse box. Just need to be able to send the correct data to the gauges.

To make life easier I plan to tap in just before the ECU and run it through the same firewall.
 
This is lambda sensor before the cat wiring to the ECU

Oil pressure switch wiring to the dashboard

Oil temperature sensor is digital signal, so useless for your analog gauges.
