I am changing the 2 rear HO2S sensors this weekend because that nice man 'Waders' checked them for me at the last Herts meeting, before I start does any know if the colour of the wires on the orignal sensors are the same as the new ones from Cats direct ? they are the 4 wire type, the instruction in the box don't show the colour code for Fords.
Thanks
Keith

HI,
Only checked the colours of my sensor the other day in preparation for similar situation, except mines a 2.3 with only one pr-cat sensor. Anyway, the colours are
2 black
2 white
This probably means the whites are + and the blacks are -, one pair for heater and one pair for sensor. This is only an educated guess as I have not actualy removed the old one yet.
HTH
Regards
Pete

I changed the sensors over the weekend and there was 2 white 1 black & 1 grey wires the same colours as the new ones from Cats Direct so straight foward in the end apart from having to heat up the thread to free off.
