I recently bought an Apexi turbo timer that has a built in AFR metering capability. The instructions are not toally clear about how to connect the wire to pick up the signal feed from the Lambda Sensor. Rather than risk buggering an ECU, I thought it would be a better idea to run the cable onto the wiring from the Lambda sensor.

Mine has three wires coming out of it, can anyone tell me which one to tap???

would appreciate if you could text a response to 07795607553 as I am about to leave to travel to my garage.

Thanks in advance.
