Title: O2 sensor wiring
Post by: MR-S Turbo on August 23, 2005, 16:16
I have got a A/F ratio gauge and need to know which O2 sensor to connect it to and also the wiring diagrams for them on a J Spec car.

Thanks

If your taking the signal from the ECU then tap into the wire going to E4 pin12.

JSpec has the same wiring as all the other models.
