Racetronix,
I went to your site to buy these but when I clicked on the link that allows you to buy both of them, the price comes up as $69.98. The individual prices are listed at 29.99 for the knock kit and 24.99 for the cam kit, for a total of 54.98. Where does the extra 15.00 come from? Shipping and handling as listed at $0.00. I did not think it was shipping since it shouldn't even be close to 15.00. Then I thought maybe it was Canadian dollars, but is says USD.
Edit: Okay I went back to the web site and clicked on the option to buy each one individually and I see that the 15.00 is for shipping and handling. If you buy them separately for whatever reason, you will get the 15.00 charge for S&H twice. I could not see the shipping and handling charge listed on the page where you order both (cam and knock) together because the description of what you are ordering is cut off and the shipping and handling note is there and not where it actually says shipping. I just shipped a relatively heavy ATI F1R head unit from Texas to New Jersey for $20 with $3000 in insurance. Why is the shipping so costly? Is this overnight?

I didn't think he was putting down the vendor until you mentioned it. It's nice for other's to be able to see that there is an economical solution for those more talented, or time to do it.
I already had some experience doing this when I helped Andy out on his motor going into his old C6. It really is no big deal.
But there is nothing wrong with somebody coming up with easy PNP parts. In contrast, just because somebody points out that they can do it for $3.00 does not mean they are bashing the vendor for producing something that does the same thing for $65.00. It's just FYI.

The material cost for our harnesses is above $3.00 esp for the knock sensor relocation harness. Silver / Teflon wire and FB loom is not cheap.

Thunder Racing should have these in stock late this coming week. Shipping from their location in LA would be much cheaper if you can wait the extra few days.

LS1 Sensor Description
This knock sensor (KS) system uses one or 2 broadband one-wire sensors. The sensor uses piezo-electric crystal technology that produces an AC voltage signal of varying amplitude and frequency based on the engine vibration, or noise, level. The amplitude and frequency are dependant upon the level of knock that the KS detects. The control module receives the KS signal through a signal circuit. The KS ground is supplied by the engine block through the sensor housing.
One way the control module monitors the system is by output of a bias voltage on the KS signal wire. The bias voltage creates a voltage drop that the control module monitors and uses to help diagnose KS faults. The KS noise signal rides along this bias voltage, and due to the constantly fluctuating frequency and amplitude of the signal, will always be outside of the bias voltage parameters.
Another way the control module monitors the system is by learning the average normal noise output from the KS. The control module learns a minimum noise level, or background noise, at idle from the KS and uses calibrated values for the rest of the RPM range. The control module uses the minimum noise level to calculate a noise channel. The control module uses this noise channel, and the KS signal that rides along the noise channel, in much the same way as the bias voltage type does. As engine speed and load change, the noise channel upper and lower parameters will change to accommodate the normal KS signal.
In order to determine which cylinders are knocking, the control module only uses KS signal information when each cylinder is near top dead center (TDC) of the firing stroke. If the control module has determined that knock is present, it will retard the ignition timing to attempt to eliminate the knock. The control module will always try to work back to a zero compensation level, or no spark retard. An abnormal KS signal will fall within the noise channel or will not be present. KS diagnostics are calibrated to detect faults with the KS circuitry inside the control module, the KS wiring, or the KS voltage output.
LS2 Sensor Description
This knock sensor (KS) system uses one or 2 flat response 2-wire sensors. The sensor uses piezo-electric crystal technology that produces an AC voltage signal of varying amplitude and frequency based on the engine vibration or noise level. The control module receives the KS signal through a signal circuit. The KS ground is supplied by the control module through a low reference circuit.
The control module learns a minimum noise level, or background noise, at idle from the KS and uses calibrated values for the rest of the RPM range. The control module uses the minimum noise level to calculate a noise channel. A normal KS signal will ride within the noise channel. As engine speed and load change, the noise channel upper and lower parameters will change to accommodate the normal KS signal, keeping the signal within the channel. In order to determine which cylinders are knocking, the control module only uses KS signal information when each cylinder is near top dead center (TDC) of the firing stroke. If knock is present, the signal will range outside of the noise channel.
If the control module has determined that knock is present, it will retard the ignition timing to attempt to eliminate the knock. The control module will always try to work back to a zero compensation level, or no spark retard. An abnormal KS signal will stay outside of the noise channel or will not be present. KS diagnostics are calibrated to detect faults with the KS circuitry inside the control module, the KS wiring, or the KS voltage output. Some diagnostics are also calibrated to detect constant noise from an outside influence such as a loose/damaged component or excessive engine mechanical noise.

Please confirm that the cam sensor wire swap has been done in your harness. I believe the (2) outside wires (of the 3) need to get swapped to make the LS-2 work with LS-1 PCM.
Also do you have a LS2 90 MM TB harness kit for the C5's?

We will have a FULLY PnP LS1 to LS2 TB adapter hopefully within 4-6 weeks. Prototypes are done.
We can provide the LS2 TB connector with flying leads in the interim.

I was ( I believe) the first to do the LS2 to LS1 conversion. I put the 427 in my C6 last year. I got the wiring schematics for both and figured out how to wire it. It was sort of a crap shoot. I had no idea if it would work or not, but I had to try it. I cut and spliced my own harnesses and made it work. It cost me almost nothing.
If you're contemplating swapping from LS2 to LS1 or vice versa, you are making a major investment. I have done a few of them and they work out great. The next one I do will have Racetronix harnesses on it. I'm not going to try to save $50 on a $10,000 job when that $50 will give me a clean, foolproof installation. Plug N Play is way better than Cut N Solder. Just my $.02

hmmmm i spend 45k on a super car...
i think i can afford $60.00 for someone elses time to put together a nice out of the box solution.
pat yourself on the back for saving $57.00
