I am getting itchy in not using the car so I took today off *cough cough* to fix the O2 to the car... only problem is finding the Pin out and also finding an O2 compatible to the ECU... Is all O2 the same?

O2 sensors are mostly the same - more modern cars might have wideband sensors -but unless you're paying >$150/200 dollars for it then assume narrowband.

for instance, a ford-sourced O2 sensor will do just fine for my 18R and/or 5ME

I'll include of a scan of a MX62 ECU Diagram, all I need to know is which part of the yellow ecu plugs to add the extra wire...

you''ll have to open up the ECU and look at the under side of the board to see which pics are not going anywhere.

that diagram won't indicate location in the plug.

if you're swapping ECU's you'll have to make sure that the other input/outputs are in the same place.

Here is the diagram of the ECU of the MX62 (Aus Spec). All I need to know from the plug diagram below is where the O2 pin is.

As noted previously, there's no O2 sensor in a Aus-delivered 5ME loom. There's no O2 sensor in that diagram at all

You could use one of the un-used pins in existing 5ME plug but you'll have to make sure that the ECU side of pin is not being used for something else

just got myself a 5M-E ECU from America with an O2 input

Are you sure it's not a 5mge ECU? 5ME is a primitive device - hence the engine relying on mechanical means (EGR, air injection) to control emmisions.

Can you put up a pic of this other ECU with the lid off? it should have pin in/out info printed on the upper (component) side of the PCB

Or are you trying to find where the O2 wire should go into the ECU? Should be marked on the PCB of the ECU if you get stuck there? But I thought that even the AUS 5me ecu had O2 marked on the pcb (just doesn't go anywhere?)...

on the board there is an E01 and E02 - but these are earths (5 of the pins are earths!).

My notes for the 5ME indicate (n/u = not used):
top row:
E2 - VS - Vc - n/u - IDL - Psw - TL - n/u - n/u - THW
bottom row:
IGN - E1 - VB - +B - STA - E - n/u - THA - #10 - #20 - E01 - E02

hope this is of some help.

cheers,
charles-on-holiday!
