here is the deal i just added an air/fuel gauge to my car and it says to tap into the o2 sensor wire on the ecu......i cant find a good ecu article nor can i figure out what wire is for the 02 sensor on the ecu....i tryed to go trough the sensor its self but i cant figure out what one is the rite wire to cut into aka the (signal wire)....so please help..

 

MAybe if you read the 1st couple of posts that are stickied you will realize that. your answer is in the ecu thread

if your ECU is obd1 it should be D14
