I am looking to run a new knock sensor wire from the ecu to the knock sensor. I do not what is the pin number and color of the wire to look for on the ecu.

Thanks

 

Not trying to be a smart A here... but if you haven't already located the wire and Ohm'd it out all the way to the ECU, how do you know that it needs to be replaced? There are certainly other points of failure in the path of electrical connection between the ECU and the actual knock sensor that I would be suspicious of BEFORE suspecting a problem with the main wire harness, primarily the connector at the knock sensor. If you can see some obvious trauma with the wire in question (cut or burned or otherwise broken), why not just splice/repair it at the point of failure? Do NOTE that this is a SHIELDED wire. Would advise against using an unshielded wire.

BUT, if you just have to have an answer to your question, here it is. Factory Service Manual is your friend, and it's free, online.
