Knock Sensor Wire Harness

Knock Sensor Wire Harness
Ok so I've been getting code 52 & 55 on my 92 SC400 for the past week now. I've replaced both sensors and reset the ECU but the code comes right back after a minute of driving. I'm thinking it's the harness now as they do look old. My question is does anyone know where i could find the harness. I've called my local Lexus dealership and they told me i couldn't buy the part but i could bring my car in and they could replace but that's not an option as they are asking way to much.
It's really retarding timing 100% now

Tell us the parts we need to buy.... and if anyone knows how to recreate a new harness for this... let us know.

Durvelle,
He (unknown101) has an SC300, which has no subharness..... Both you an I own the SC400, which does have the subharness.....
Unknown101, you're kinda adding to the confusion, honestly. Giving bad advise.
Durvelle, this is what you are looking to recreate, (It's a discontinued Lexus part)

I already purchased this harness pictured, unfortunately after 3 days I received an email from the website that said it was no longer available, and my money was refunded. (Same news as the dealer)
I guess the question is, what are the connector parts for this harness. I spoke to a gentleman at wiringspecialties.com on the phone on Saturday who said they have no 1jz knock sensor harnesses available, but if I can find out the part #'s for each of the connectors, they do stock the connectors themselves.
I took it a step further, and contacted O.T.L. (dude has a spare Lexus in his attic??) & he should have all that information (possibly) He's yet to message me back. So that's where things stand for me. I'm waiting to find out part #'s for the connectors, at that point I think I know a shop locally who will be able to recreate the wiring harness and install it for me.
We just need someone with knowledge to confirm connector #'s at this point since the harness itself is discontinued from Lexus....
I hope this helps.
