AEM Wideband???
Has anyone installed an AEM wideband air/fuel ratio gauge? It has two wire harnesses on it. One connects directly to the o2 sensor, and the other has four wires. What is this one for? Does this one wire to the primary o2 sensor hookup on the main harness to feed the ECU with the correct signal? Please help.

Read the instructions.... lol...
The main harness is for the sensor. Thats the easy one since it has the plug on it. The other four wires I beleive are black, red, white and blue. The black is a ground, the red is switched 12 volts. The white goes back to a ECU which is a 0-5volts output. The blue I beleive, but could be wrong because I am going off the top of my head is a 0-1.5v line. Not sure on that one though.

Yeah, the white and blue wires are for narrowband and wideband outputs to the ECU.... I don't know which is which though...
