Hi Guys,
Thought i'd found it on here before but didn't save the page and can't find it again.
I've got from my loom, 4 colours for heater power, heater earth, sensor, sensor earth.

Then from the plug i've got a Blue, White, Black, Black

Im Guessing the 2 blacks are the 2 earths, But then Blue and the White is left with heater and sensor.
Anyone able to help me out?
Thanks in advance
Ed

Have a look at the chart on this page:

I'm guessing its a Denso, Toyota or a Honda?
Black wires = heater
White = ground
Blue = signal

Im really confused, don't know what car it is off but got it off Claire on here... Am surprised that the blacks arent the earths.

Anyway, thanks for that. I will try the white, blue, black, black.
Guess it doesn't matter which black goes with the black and white/green

Yeah - Lambda wiring colours do seem to defy logic!
The black heater wires can be connected either way round.

Ahh ok brillant. I'll give it a try!
Thanks again!

As it's effectively a loop the heater wires are always the same colour so they at least easy to eliminate.
