4. WB-O2 Meter Nano Electric Installation
The WB-02 Nano has a 12-way connector with 3 wire groups. One of them has
the connector for the O2 sensor, the second makes the CAN communication
with Power FT ECU’s and the third is responsible for power and analog output.
By default, the analog output is set to values of 8.7AFR to 16.2AFR Gas, but
can be configured to 5.14AFR to 17.6AFR Gas or 9.55 to 19.11AFR or 9.55
to 58.80AFR or yet 9.55 to 146.9AFR (Gas), if necessary.
See the following wiring diagram for details about connections.
