delco conversion on toyota 4efe efi engine

[Holden202T]

My post above has the method for working out the opening times. If done properly is accurate.

I really need to do it one day for my car lol!

The toyota 02 is four wire, the camira/pulsar 02 single wire arent they,

Early commodore started as 1 wire then 2 then 4. Easy conversion.
1 wire is signal to ecu and earth through the exhaust mounti g from the sensor body.
2 wire is earth thriugh the loom to the ecu.
4 wire is same as 2 wire but with a heating element built in.

So i should be able to wire the toyota 4 wire 02 into the delco wiring of the camira/pulsar

yep.

The heating pair is just another switched 12v and ground?

[Dylan]

Ive done that before using the 12v from the speed sender supply and earth to an engine bolt.
Keeps it all in the loom as well.

So the 02 sensor will still work the same when wired like that, my car also has aircon and from wiring diagrams ive found the aircon seems to be wired into the ecu, could the air con be wired into the delco as well
