need help running new wire to ecu from knock sensor

[tbonitz301]

Hey guys ive been trying to cure my 3.2* of knock, and i have replaced the sensor. So my guess would be the only thing left to do would be to run a new wire from the knock sensor to the ecu. Do i just run the wire from the KS to pin 78?

Yes.

Ok. I'm gonna go try it. Hopefully it works so i can start tuning

The knock sensor wire needs to be shielded.

you can buy a shielded wire from Radio Shack if you dont already have one. Just get yourself a 5-6' wire to be safe.

You guys may have just figured out the problem. I noticed when i replaced the old sensor there is nothing protecting the wire coming out of the KS. It probably got hot and melted which is why im seeing the default reading for knock

OK. Well now im not quite sure what to do now. I see that the heavy gauge wire running from the KS splits out to a red wire,and black wire, and then once it goes through the plugin they come out white and black on the otherside. Which of these do i need to hook into. Thanks for the help
