Hello,
I just bought these and cant find out which wire is which??
White, White, black and grey.
Anyone know which is 12v+ ign, grnd, and sensor wires??
I am doing a swap into an AC cobra which currently has no ecu loom for 02, so will pin according to wires from sensor etc.
Many thanks
Regards
Gav

Gav, how are you installing all this into this vehicle? Are you using an aftermarket custom wiring harness?

Gav

Hi, yes its a schwanke? Loom with no oxy sensor in it, i have to install these to get it through my iva £500 a time test so would like closed loop reinstating for this test....
ecu is ls1 b 0411 and just need to know which wire goes where from the bosch sensor into the pcm,

Hi,
I think i may have it, just need someone to confirm sounds right,
on this page
ricksfreeautorepairservice.com/p0134/
it shows common oxygen sensor wires and for Bosch,

two whites are heater(C+D), grey return grnd(A),black ref signal.(B)
so i attach A (grey) which is grnd to the body of sensor to pcm 29 c1 blue, and 26 for bank 2,
then B(black) to c1 pcm 69, and 66 for other sensor on bank 2,
then c on both oxy sensors go to a grnd on vehicle,
and d on both sensors to 12+V ign.

Hope this makes sense??

HUH?!?

Oh, right, you're from UK so I won't understand your English.

I have a cousin Gavin somewhere around London...

Anyway, I think you have the wiring correct in that list.

Thanks so much Paul for helping,
i will give it a go early next week as off a few days.
