I've just installed a turbo on my 98RS, and i've also removed both cats. I was going to install the pony express CEL fix, except I realised that my rear O2 sensor has 3 wires (white, white, black), rather than the 4 wire O2 sensor. Is there different CEL fix for the 98 O2 sensors?

Thanks,

Mark.

Yes, there is, I was never able to find the correct schematics for mine.
