I finally got round to building John Banks's DIY AFR Meter this weekend, using the connector diagram for B136 to find Pin21 from http://www.mrtrally.com.au/performance/docs/WRX-V5.pdf page 33, describes the connector as being blue. On my MY97WRX all 3 connectors to the ECU are yellow, and have 2 rows of pins not 4 as in the diagram from the above PDF document. Has anybody else fitted one of these devices to an import? if so could you describe the necessary connection for the input to the AFR meter?.

Thanks.

 

Pre My97s have different ECUs & connectors.

Check out my home page (see profile) for earlier ECU Pinouts.

Cheers m8.
