Hi all,

I've recently done an engine swap in my EB (replaced the old HO with a low km AU motor), and in the process I have also removed all of the LPG wiring from the car, as I won't be running it on the new motor.

I have got everything sorted out, except for just ONE wire, and I need some help as to where/what it should be doing. I have looked through my service manual, as well as the diagrams and schematics available online - with no joy.

The wire is located in the white, round ten-pin connector that normally clips onto the back of the throttle body. It is located between the yellow wire, and the black wire with a white trace line. See picture for reference.

The body-side of this wire (not the engine loom side...) went down to the passenger side O2 sensor, but is was soldered on to one of the wires of the sensor, and is definitely not a factory looking wiring job. It looks like some of the LPG wiring, but doesn't actually tie in to the now removed LPG system.

Does anyone know what this wire should be doing? It doesn't make sense to hook it back onto the sensor, because the car's loom already hooks into it.

Hopefully all of that makes sense.

Cheers,
Coxy
