Hey guys, I just picked up an arm wideband 02 sensor and I'm really lost as to what pin in the ecu I connect it to. Right now I have my wideband connected to the #4 pin on the large ecm connected (its a white wire) , and now my car barely runs or idles. Did I connect it to the wrong pin? Anyone able to give me some guidance?
