Knock sensor connectors?
 

I just went to my local toyota dealer and I asked for some knock sensor connectors. They said they didnt have them and that I had to buy the whole wiring harness, which is very expensive. Where Can I get some knock sensor connectors???

You might find the plug in here under 1 wire female connectors.

No guarantee if they are still being made though.
If your around Phoenix, call all 6 dealers around there and see who is willing to help once you get the right number and make them your freindly neighborhood dealer.
Or just go to ecology, pick and pull or U pull it and get one from there.

Bill's link is better, the plug numbers don't even show up in my link, the one that might work is plug number 90980–10197. Try and cross reference them at the dealer.

Thanks guys.
