K20 Issues/Questions

18 Aug 2012, 3:41pm
Hi All,

I'm after a little help with some wiring.

I am in the process of trying, at long last, to wire in my air-fuel ratio sensor but struggling with the diagrams and what wires go into what pins on the ecu etc.

Does anyone have a simple way of explaining what wires from the sensor go to which pins/plugs on the ecu?s

Secondly has anyone yet supercharged or tweaked their K20 and if so which way/products have been used?

My car will be out on track shortly, now that I have the money to finish it off & all being well it will be raced next year.

Hi Jono,
I've got a wiring schematic for the install I did. Feel free to drop me a PM with your email address and I'll send it over, but for starters the O2 wiring is:

Black/Orange = Heater Power. Connect to switched 12V
Black/White = Heater control. Connect to engine harness pin 10
White = signal plus. Connect to engine harness pin 19.
Pink = signal minus. Connect to ECU "E" connector pin 4.

Don't forget to earth the shields. Good luck!
