or even help to find a new loom on ebay as i cannot for the life of me find the correct one

i would appreciate any help given

thanks in advance guys

First things first, which sensor did you change? The one on top of the manicat, or the one further down, at the start of the front section of the exhaust?

Fault codes point to the second of those.

Wiring:

blue/red wire on pin 1 of the 4 way is a switched 12V from fuse 31 (heater supply power)

brown/white wire from pin 2 of the 4-way goes to engine ECU pin 13 on the 52-way conn. (modulated earth for the heater)

grey/white wire from pin 3 of the 4-way goes to ECU pin 21

grey/red wire from pin 4 of 4-way to ECU pin 47

Those are the colours on the loom side of the 4-way connector pair. The sensor wires are probably different colours for the section to sensor itself.

you sir are a legend thank you!

i replaced the second one at the bottom checked fuses and was then lost as i didnt want to start pulling the loom apart if i can just test the wires was thinking about just mapping it out but want to repair it
