Wow, that was fast. That's almost exactly what I needed. I have a DX sensor so the parts are already available to me, but...
The problem is that my DX ECU is looking for voltage on the heater circuit, so I actually have to wire it in on the harness and it's not covered in that FAQ. I'll still get a CEL. If the CEL is on, won't my ECU stay in open loop (safe mode)?
The engine harness to the ECU is complete, but where it connects to the engine harness in the bay, there are blocked off connectors. The CX harness is the same as the DX, it's just missing some wires. If I match the ends up, it will shut the CEL off.
