Hello i found the ECM to my 2002 hyundai elantra. I see all the wires but there are more then 1 blue wire. How do i figure out which pin is 66? Does anyone have a picture to tell me or specific details to which harness it is. thanks ------------- Jonathan jonbr84@hotmail.com

Sorry no PICS.
There are numbers on the ECM plug. May be #1 at one end and #85 at the other end. you need to make an educated guess at which blue wire is in the correct spot.........(ie.) Maybe a Hyundai mechanic could help

I have a question. when you open the driverside door and that kick panel there, under it is all the wires to the car. There is a large bundle of wires. is the tach wire in there? There are 2 blue wires, on is very large and has some black marks on it, and there is a thin blue one.. will one of these work?
