Hi guys, havent been on in a while, but ive started work on the mini again.
While fitting a new y piece, im extending the wiring for the o2 sensor.
But ive mixed the 2 white wires up, now im not sure which one goes where.

Can anyone help me?
I have the original connector that attaches to the wiring loom, and the sensor obviosly.
There is 1 grey, 1 black and 2 white, please could someone let me know which goes where.

Thanx folks

Alright mate, hows it going? Really doesnt matter? Oh, ok, i thought i read somewhere not to get them mixed up. Ah well, i can tear on with that then.
Thanx for the reply!

Alright matey, got that misfire sorted yet???

See attcahed diagram, it might help?

I'm assuming 2 wires are for sensor reading and 2 wires for heater?

That's a neat little image! Where'd you get that?

Anyways, yes - The Blu/Red (C164-4) wire is the +12V for the sensor heater. The black (C164-3) is the ground of the heater. The Grey (Silver) and Light Green/Grey (Silver) are the 'data' wires that lead to the ECU. Looks like the Grey wire should be in the socket position #1, LG/S should be in the socket position #2, and the #3 is Black (Ground) and #4 is Blu/Red.

Of course, that's according to the diagram you provided. The colors in your Mini could be - and probably are - different.

Coyttl, it's from the Rover Manual (CD version). You can buy it off eBay for a couple of quid.

PS - Slate (Gray) is +ve and LG/S is -ve

Very cool, thanks! I wasn't sure which one was which signal to the ECU, so I didn't say anything. I have an SPi, not an MPi, but my wiring is pretty similar, I've found in posts back.

Cheers!
Mike.

Did the same thing myself a while back Tony, tried the wires both ways - no difference, they were a bugger to solder though. If you want to save some hassle, I got a lamda from an old k-series rover they have the same wires and connection plug but they are longer and I got mine to fit without cutting.
