okay guys...sorry for the noob question but i'm confused and lost. I was on the AEM forum and they told me to hook up 4 wires (1 to negative of battery, 2 ignition switch, 3 sensor wire to ecu, 4 ground wire to ecu) while some other are telling me to only hook up 3 wires(1 to negative of battery, 2 to ignition switch, 3 sensor wire to ecu). Is there a difference in the way the WB will perform if installed differently?

I really need to install the WB correctly before i go about calibrating the thing. then i'm gonna need some help as well as many people have had problems calibrating their WB with the EMS i've heard.

oh and lastly...if there is another wire that goes into the ecu, what color is it?

any input will be greatly appreciated!!
