Re:CEL

You know............I think a DX has a 4 wire O2 and my CX has a 1 wire. Are 4 wire O2 sensors heated-sensors?
Is that why you asked how many wires, Dr.Boost

Re:CEL

Yeah, the heated ones are 4 wires. The one on your car is a one wire? That is most likely the problem.

Re:CEL

I have a 4 wire O2 sensor but how the hell could I hook it up? Do you know where the wires go, what they do, or know where I can get a wiring diagram?

Re:CEL

Two black wires are for the heater, the white wire is the sender to the ecu, and the other is power.

Re:CEL

No. I believe they connect to the ecu.

Re:CEL

See I didn't think they would because I compared ECU's before I swaped them and the have the same pins in the same locations. Unless theres an untapped harness on my firewall.
