    I have a 96 HX coupe which has 2 O2's a 7 wire and a 4 wire. I swaped out the hx motor with an EX motor but still used the HX harness. I am runing a EX ecu now also and want to know if i can convert the 7 wire to 4 wire O2 and if so how can it be done? Thanks

    Is there a way to distinguish the senosr voltage from the heater control? I believe they're both black wires.
