I got a single cam turbo hatch now finally up and running but I need a 4 wire o2 sensor but my cx hatch has only a 1 wire o2 sensor so how do I convert it to a 4 wire o2 sensor? Thanks

 

someone has to know

 

because the cx harness is factory 1-wire....

Here's the pinout for that

its really simple, actually - youre just going to need 4 ecu pins, inserted into the ecu plugs, then just extend the wires to the sensor - I suggest you get a 4 wire harness, and wire that into the ecu, so youre not dinking around with the sensor's wires everytime it goes bad
