Audi AAN 5cyl 20VT engine
Please measure the MAF pins in the harness
- which AANpin it belongs to (fill in table below)
- any pin connected to ground must be avoided.
- Is there a +12V pin (capable of 2..3A) for heater+ ?
Can you fill this in ?
Pins to use for WB02 Meter:
- 1, AANpin...#37 (12V supply)
- 2, AANpin...#42 (open on stock harness)
- 3, AANpin...#43 (open on stock harness)
- 4, AANpin...#51 (open on stock harness)
- 5, AANpin...#54 (open on stock harness)
- 6, not used
Using these pins we wouldn't use the MAF plug, but would allow there to be enough inputs for the WB02.
In the meantime, review VemsAudiAan
