Hi Guys,

Trying to wire up the O2 Sensor to a Hybrid Hardness in a DC2 with a K20
Denso 192400 is that number thats on it and its the Primary one that I took off the car,

this is what I need to know

The Wires on the O2 Sensor are BLACK BLACK WHITE GREEN
the hybrid harness wires are YELLOW RED WHITE GREEN

Ive also Tested the wiring it

GREEN to GREEN
YELLOW to BLACK
RED to BLACK
WHITE to WHITE

but keep getting cell light for Primary Senor when using diagnose tool

Please help

This little pic is the wire side of the primary O2 sensor plug. Clip is above the 1 & 2 positions. Pins & plug facing away. Wires coming out towards you.

1 2
3 4

The 4 wires on the Primary O2 need to go to:
1 - Primary O2 signal +
Continuity to C101 pin 19 (from there the wire goes over to ecu A6)
2 - Primary O2 ground -
Continuity to C101 pin 13 (from there the wire goes over to ecu A16)
3 - Primary O2 Heater signal +
Continuity to C101 pin 15 (from there the wire goes over to ecu A22)
*NOTE: This wire is also divided and leads into a relay. I plan to add the relay information a little later.
4 - Primary O2 Heater ground -
Continuity to C101 pin 10 (from there the wire goes over to ecu pin A1)
However In some swap harnesses I have seen this wire pinned directly to K-series ecu pin E4. That also works as an appropriate heater ground.
*NOTE: 1 & 2 MUST be wired to the above correct locations for Kpro to properly read and display the A/F readings.
*NOTE: 3 & 4 Can be reversed. The heater will still operate without a problem.

I don't have the plug thats the problem if I had the plug on the O2 Sensor I could of just plugged it into the K Swap Loom but when the O2 was removed from the DC5 the plug was stuck on the Subframe and the wires were pulled out so thats why I need to know what colour wires went where

Thats the best pic of that Ive seen so far google brings up O2 with Blue plugs and its got Blue wire instead of Green.

Thanks man going to put the wires back into the plug today and give it a try hope no more Cell light
