o2 sim question
I have an 04 coupe. I have installed kook's lt's w/o cats. I'm running o2 sims. The connectors which originally came on the sims did not mate to my harness connectors for my rear o2's. I installed the the connectors off of my rear o2 sensors onto the end of the sims. I am getting a p0141 and p0161 code. This code is improper rear heater circuit. I'm guessing I have one of the wires on the sims crossed. Can anyone tell me which two wires on the sims or the harness are responsible for the heater circuit?
TIA.

Disclaimer, I don't have a manual, but I have a good book with wiring diagrams etc. and it only goes up to '01...that said.
For each sensor I'm showing
Brown - power to heater in
Black - GND out
Left Rear -
- Purple/white - high
- tan/white - low
Right Rear
- tan - low
- purple high
If you can't see colors, this is what I have for the harnesses:
Left Rear (harness clip at 12 o'clock looking at the pins
A(low) C(GND)
B(high) D(power)
Right rear, large tabe at 6 o'clock
D(power) B(high)
c(GND) A(low)
Hope these colors match up to what you have and this is at least somewhat helpful.
