    Repining the 93 harness would work. How many O2 sensors does the 95 use? Any chance you could get the O2 sensors out of the 95 then swap them into the 93? You could just run wiring down to the O2s from the repined connector. If you could get it working no need to have the 93 ECU repaired.

    Are you absolutely sure are the terminal pins on the 93 and 95 are configured exactly the same except for the O2 heaters? Could be a costly mistake if they aren't.

    You are so right. I have a 2020 TRD sport CM with no modification. I am averaging 17 mpg in the city with every recommendations you have listed.

    That very good for city driving. I always measure my mpg on the highway. I don't even look at the mpg with city driving. There are just too many variables. I usually see 21mpg on the flat and if I keep my speed at 65mph. A friend of my has a 2018 Platinum 4X4 CM and he sees the same mph. Mines a 2020 SX 4X4 DC.

    Right now I'm about 90% sure they're the same for the exception of the heated oxygen sensor. I will continue to research thoroughly before I swap them.. did find a PCM pin readout that is for 92-95 since they're OBD1, but will go down pin for pin to verify... it has 2 oxygen and 3 post cat oxygen sensors
